Pool Operation


Pool water is pumped to a filter, dirt is then trapped/filtered and "cleaner" water returns to the pool.

Pool water is treated/sanitized  98% of the time with chemicals,  maintaining healthily levels of PH, Chlorine, Alkalinity and Hardness is the goal.

Pool Opening

In the upper northeast many people open their pools on Memorial Weekend. This is a good time to get the pool up and running.
This involves:
  1.  Remove any debris that may have accumulated on the top of the cover, use of a leaf net attachment on the end of your pool service pole should work fine. But do not fully extend your service pole if you are getting even half full bags of debris, or your pole will be ruined/bent. (skimmers are for suckers), say it with me, skimmers are for suckers, very good. Always use a leaf net.
  2. Now you should pump off water that has accumulated on your solid pool cover (mesh safety covers will not have this concern). There are several good cover pumps available for under $80.00. It is most important to get any debris that might fall into the pool, anything left on the cover with water is going in the pool and will need to be cleaned out. It is usually easier to do a good job of cleaning off the cover, than getting crap out of the pool!
  3. Do a ritualistic pagan dance for the gods, and pray the water is clear under the cover.
  4. Remove the cover!
  5. Begin adding water, filling the pool to the correct level (usually the center of the skimmer).
  6. Now remove all winter plugs and skimmer Gizmos. All skimmers should have some kind of plug that needs to be removed, as well as all the jets on the pool walls. 
  7. Reconnect pump and filter housings if they were removed, and plug in the pump.
  8. Prime the pump by removing the pump cover and pouring in a bucket of water.
  9. Open valves and turn on the pump. If you have a DE or Cartridge filter, they should be disassembled and cleaned before use.
  10. Check water balance, usually the PH and the Alkalinity are low to start. Low or high, use appropriate chemicals to adjust to proper range. (I like Namco's ABC pool balancer for low alkalinity)
  11. Super chlorinate the pool water. This means putting in a lot of chlorine. Read packages for proper use, amounts to use, and application. Powder chlorines can pile up on the bottom of your pool and damage your liner, (you should carefully *mix powders in a bucket of water before disbursing into the pool).
  12. Vacuum your pool thoroughly - I HIGHLY suggest you vacuum for the first time to waste, you will lose a lot of water, but the pool will be ready in a week or even days to swim in!
  13. Install hand rails and ladder, The part of the ladder that presses on your pool walls should have rubber fittings (pools with vinyl liners will cut and leak if rubber ends are missing from ladder).

Pool Closing

  1. Do not close a dirty pool.
  2. Don't give me excuses, clean the dam pool. (hehe)
  3. Lower the water a  inch below the skimmer.
  4. The only chemical I recommend using at closing besides line anti-freeze, is algaecide.
  5. Blow all lines out with air (a shop vac will suffice for all but the bottom line) you will most likely need compressed air (once you get air bubbles from the bottom line close valve to trap air in the line), if you do not believe all the water is out of upper lines, pour pool line anti-freeze in. Water trapped in a line or skimmer will expand when frozen, and crack your lines or skimmers.
  6. Put caps or plugs on all jets on pool walls. If pool returns are still under water, blow air through till bubbles come and stuff a rubber plug in while still bubbling.
  7. Put cap or screw a gizzmo into skimmer inlet pipe under basket.
  8. Drain filter and pump housing (look for and remove all drain plugs). If you can disconnect these and bring them into the basement all the better, if not be sure to cover them with at least a trash bag..
  9. Remove chairs and tables that would be in the way of a pool cover
  10. Remove hand rails and ladders.
  11. Put in / string up appropriate winter air pillows/ ice pillow, I recommend using these on in ground pools too. Above ground pools there is no option, put in a air pillow.
  12. Now you are ready to cover the pool, If you are using a tarp style cover make sure there is enough slack in it. Remember the cover will collect rain water and will pull into the pool some. If you have a mesh safety cover, use the appropriate allen tool and turn the safety cover anchors counterclockwise till the are raised 1 - 1/2 inches. You could keep some buckets of water around to hold safety cover in place while it is being installed.

Pool Cleaning / Maintenance

  1. Check hardness and alkalinity every 6 weeks after they are set. Many home owners don't ever bother with these two. If you have well water it might be more of an issue.
  2. Keep your chlorine level above 2ppm and you will never have algae problems. I recommend keeping a chlorine tablet in the skimmer for every 10,000 gallons of pool water to maintain a healthy level. (You will hear some people say not to put them there, but they are stupid)
  3. If you get a lot of rain or have heavy swim loads (namely little kids that pee in the pool) super chlorinate with a high dosage of chlorine.
  4. Maintain PH Level as well, low ph and really high chlorine are the reasons your eyes may sting.
  5. Vacuum once a week for a super clean pool and by weekly for average.

How to Vacuum Pool

Your pool should be running.
Put your vacuum head on your pole, then put the hose on the vacuum head, some hoses should only go on one way, read your hose end, if it does not say, then is should not matter. Now put the vacuum head under water and put the entire hose in the pool, take the other end not on the vacuum head and put it over a return jet on the side of the pool and fill the hose with water, you should see all the air leave the hose as it fills with water from the pool jet. Once all air is out of the line, you have the line primed. Now take the same end you filled the hose with and bring it to the skimmer (basket should already be removed), put the hose through the opening in the pool and right into the hole in the bottom of the skimmer, some skimmers have to holes, only one will be sucking water from the pool. Now either you had to much air in the line and lost the prime at the pump or all the water is now being sucked through the hose along with the dirt. If you have two skimmers plug or shut off the second skimmer, same goes if you have a bottom drain shut it off. This will concentrate all the pools water through the vacuum and give you powerful suction. Move the head slowly so you don't disturb the dirt, if you move to fast you wont suck the dirt out of the pool, you will only mix it into the water.

Some Signs of Algae Growth

If you see any green spots forming between vacuuming, take a brush on the end of a pole and scrub it mixing it with the pool water, this way it has a chance to mix with chlorine and die or get cleaned in the filter. If you have these green spots, maintain chlorine at higher levels. algaecide s are for suckers.

How to Clean a Green Pool / Kill Algae / See The Bottom of Your Pool in 3 hours - 4 days, Super clarity in a week

Ok, so you have a crazy swamp forming and or heavy algae all over the place. Maybe you have been doing battle for weeks or months and you can not get the dam thing clear? If you can still see the bottom of your pool it will help, if not, it still is not that bad. You have probably spent a small fortune on clarifier and algaecide s, and brought your water to be analyzed by the so called pro's. I am going to tell you the straight truth, and if in your undying gratitude you want to send me a small gift (please no more than five dollars), Mail it to: Mike Kern 51 James St, Tewksbury, MA 01876, if you have a Paypal account simply use my email mike@poolservicema.com. Also please leave us a review on Google Maps

Through out test strips and only use a chemical test kit, for ten dollars you can buy one that does Chlorine, PH, Alkalinity, and Hardness. Now test the water!
  1. Over fill the pool, go right to the top edge of the skimmer, but no higher. 
  2. Now balance the PH, do what you have to: use ph increase (recommend Namco's ABC product) or ph Decrease to get proper ph balance.
  3. Shut the pool off for 24 hours! Yeah stop running it, your mixing the dirt into the water. Please for the love of all things good, let the crap settle to the bottom.
  4. Do not stir the pool by brushing the bottom or the sides! Do not stir the stuff on the bottom anymore than you have to.
  5. Before you can complete my process, you have to know one simple truth. How much shit is really on the bottom of that pool. Take your longest pole and put on a leaf net / bag. Now slowly drag the deepest part of your pool, very slowly. If you have a lot of leave on the bottom, you may want to drag that leaf net blindly until you get most of them up. This will stir a ton of dirt and algae into the water, but if you skip this step you may have to stop vacuuming every 2 minutes to clear the leaves from the pump basket.
  6. Ok, not to many leaves? Good! Or, Holy shit I think i got most of them out and waited 24 hours? Proceed to next phase of the plan.

Here is the plan via the scorch the earth I don't care about the environment, I want a clean pool.

Back to top
Dump in five gallons of liquid shock (don't use powder) per ten thousand gallons of pool water, do not dump it all in one spot, walk around the pool slowly and carefully pouring it in (I assume you are aware of all safety precautions and are wearing all necessary protections). I don't use any precautions but, I know what the hell I am doing too. hint: chlorine will bleach your shoes and clothes, or burn your eyes out! (be smart)
  1. Now the most important part! Vacuum the pool very slowly, but not to slowly, move just fast enough so you are not stirring the crap into the water (do not use a robot!). heres the trick though, vacuum straight to waste, or with the bottom filer drain open and the pool return lines closed! This way, all the crap we let settle to the bottom is sucked straight out of the pool, along with a shit load of chlorine we added. Start in the shallow end where visibility is likely better, and be time you get to the deep end you may be able to see better. You should be done vacuuming by the time the water level reaches 1/4 of the way up from the bottom of the skimmer.
  2. Run the filter and keep filter media clean (media = sand, DE, or cartridge), also maintain high chlorine level and regulate ph balance as necessary. 
When I show up on the job, I have already asked the home owner to over fill their pool and leave it off for a day or two. I bring my own pump, vacuum accessorys, ph adjusters, and a shit load of chlorine. I can usually see the bottom before I leave, if not I will follow up the next day with more chlorine. The pool will not be swim-able for about 3-7 days (to much chlorine). But the suckers clear. Keep in mind it is really difficult to over chlorinate a pool, but if you keep it that way for to long you run the risk of bleaching your pool liner. If you are not clear with in a day or two, you my friend have a filter issue!

Here is the plan while "not"scorching the earth. (Green Pool Cleaning Method)

  1. Do everything the same except, put the chlorine in after the vacuuming. This is the way I like to do it, it takes the pool 2-3 hours longer to clear, making the vacuuming a little tougher, because you can't see what your doing as well come the second hour of vacuuming.

Filter Operation and Maintenance

DE Filters (Diatomaceous Filters)

Here's the deal, if you looked at the earth under a microscope you would see tiny holes in the earth. As the water from the pool passes through these tiny holes it traps dirt. When the holes are clogged with dirt your filter pressure will rise. When the pressure is high (7-10 pounds high than when you put in fresh earth), you need to either replace the earth (Back wash & Put in new earth at the skimmer), or regenerate the earth in side the filter. Read instructions on filter house for proper regeneration.
If you do not know what your pool PSI (pressure) should be. Replace the earth in the filter and record PSI. When PSI goes up 7-10 lbs, back wash or regenerate. If you regenerate and it goes right back to the high PSI, replace your earth.
When opening the pool, your earth may need to be replace 2-3 times in a 8-12 hour period.
Once the pool is clean and clear, you may not need to replace your earth for a month.

Cleaning and maintenance of a DE filter

  1. Turn off the pump.
  2. Close or cap all the lines coming from or returning to the pool (especially above ground).
  3. open vent (on top of the filter housing)
  4. Open discharge line. If you have a bump/regeneration handle, I recommend bumping and letting gravity empty the filter, refill, bump, and gravity drain 3 times. If you have a multi-position valve, turn to backwash and run pump until site glass is clear or 1 minute, then turn off pump,  turn valve to rinse, run pump for 10 seconds, repeat this process two more times. (shut off pump in between steps).
  5. Now that we have the dirty earth out of the pump, we need to replace it (With multi-position switch filters, make sure switch/valve is set to filter). Run pump and put in the appropriate amount of earth (read filter for specifications). About 5-7 coffee cans should suffice with most DE Filters. The earth is added at the skimmer, do not disperse earth into the pool water. Now record PSI (pressure) and monitor. on average the pressure/PSI in a filter with new earth is about 7-13 lbs. A dirty filter runs at a pressure above 17-20 lbs depending where it started.
  6. DE filters should be disassembled and cleaned at least one a year. I will usually do this once a year at my house, and it happens after I open and clear my pool.

Sand Filters

Sand filters are probably the most common type of pool filter. The sand does not need to be replaced for about 8-10 years. The way these filters work is by grabbing the dirt with sharp edges. Once the edges of the sand become rounded or are not sharp, the sand will become ineffective, and should be replaced. Small sand filters hold on average 50-100 lbs of sand, and large sand filters about 250-400 lbs. Sand filters are the least efficient, so opening and clearing a pool may take a while, be sure to back wash and rinse often. One advantage to sand filters are you do not have to replace the media, so you can clean it as often as you like and you only loose some water.

Cleaning and maintenance of a sand pool filter

  1. Turn off the pump.
  2. Close or cap all the lines coming from or returning to the pool (especially above ground).
  3. Turn multi-position valve to backwash, and run pump till site glass is clear or 1 minute.
  4. Turn off pump.
  5. Turn multi-position valve to rinse for 10 seconds and run pump.
Repeat this process at least one more time and turn multi-position valve to filter.

Cartridge Filters

Cartridge filters are the most effective filters types for maintaining a already clean pool, especially when combined with variable speed pool pump, however these filters can be the hardest to clear a dirty pool with. To clean them, you have to disassemble the filter housing, and wash the filter. These filters, often made of a paper product trap the dirt on there surface. There is no media to replace except the filter cartridge it-self, and replacement is only required if there is a rip or tear.

Cleaning and maintenance of a cartridge pool filter

  1. Turn off the pump
  2. Close or cap all the lines coming from or returning to the pool (especially above ground).
  3. Open vent at the top of the filter.
  4. Drain Filter.
  5. Disassemble and clean filter.
  6. Reassemble (making sure to lube all rubber o-rings).

Pool Equipment

What equipment will I need to maintain my pool? With so many people purchasing new homes in the last year (2009), I get this question a lot. Everyday I got a call by at least one person who said, "I just bought a house, can you clean my pool and tell me what I will need to maintain it"  (literally).


So heres a list.

Pool service pole, leaf net, vacuum hose, vacuum head, Chemical test kit (not dipping strips) chlorine tabs, Ph increase, and shock. For opening and closing you may also need PH Minus, and algaecide.
