Frequently Asked Swimming Pool Care Questions & Troubleshooting


Why does well water make my pool water turn green?

Adding well water to your pool to top it off or fill is a common issue and typically can add metals to your pool. Depending upon your area (our for example is heavy in iron and manganese) metal deposit are put right from your well to your pool. It is common for those with water softeners inside their homes to think that it would not be an issue but most of the time your outside spigots are not connected to the softener so you end up with metals. A Greenish/Limish color is usually a sign of copper which can be eliminated by using a metal sequester chemical found in your local pool shop. Follow the label directions as far as PH levels, amount of time to continuously run filter and make sure you backwash after time suggested otherwise the metals can filter right back in.

Help, my PH and Alkaline levels are sky high?

The chemical to use to lower your PH and Alkaline Levels would be Sodium Bisulfate or PH Down. While the pool is running broadcast 1lb per 10,000 gals of water and apply this daily as needed till in proper ranges i.e. PH should be min 7.2 Ideally 7.4-7.6 maximum 7.8 and your Alkaline ranges min 60 Ideal 80-120 and maximum 180. I am not sure how you ended up on the high end but something to consider in the future is to add chemicals as labeled, one to two pounds at a time only you can always add more if necessary to bring your pool to correct levels. Also, certain factors can cause your PH levels to change including the following:
TriChloro sticks or tabs -lowers PH Bromine Tablets -lowers PH
Liquid Shock, Super Shock and Lithium -raises PH
Fresh plaster can raise PH
Adding Water or Rain can raise or lower levels
Swimmers and swimmers waste lowers PH

***Please note Muriatic Acid can be used to lower PH levels as well, however I would stress that this is a very potent chemical and I would not suggest a homeowner use this as a solution or store this on premises and is usually used in commercial pool situations under controlled circumstances.

How often should we change the sand in a sand filter?

We suggest changing your sand every 3-4 years. *Remember to fill the filter tub at least 1/2 full of water before pouring new sand into the filter this will help prevent cracking the elements inside.

How do you determine Surface Area of your pool?
To determine your pool's surface area in square feet use the following:
Round pools Area = RXR x 3.14 ex if the pool is 24 round take 12x12x3.14
Rectangle Area = LxW so a 20Feet x30Feet Rectangular would be 20x30=600sft SA
For those pools which are odd in shape Area = (A+B) xLx.45 A & B being the width in different sections if different in dimensions
On the web you can usually find calculators that will do this for you.

How do I clean the line at the water level around the inside of the pool?

If this is at the water line of the pool it sounds like what we call a scum line and can be easily cleaned with a pool product called Tile and Vinyl cleaner which you spray on and then wipe off. This works well also for the top of a Vinyl liner that is supposed to be white but usually has some mold right at the top where it goes into the coping. Just be careful not to use a hard wired brush or anything abrasive. I have also used Sodium Hydrogen Carbonate (Alkaline Increaser) using a wash cloth or sponge and it cleans the line nicely as well.

What type of sand should be used for a Sand Filter?

We suggest using the White Silica Filter Sand or Brown Filter Sand (white is my preference). These can be found at any local pool store. Remember before pouring new sand into tank to fill tank at least 1/2 way with water to break the fall of sand onto the filter elements. I like the white silica because it comes cleaner and usually a bigger grain so it filters better (my opinion) I have had brown sand delivered and it has had fleas in it before again just my preference.

How can I tell if I have Green Algae?

Green Algae is one of the most common of all the algae’s and easily treated with Algaecide and proper chlorination. Many times you may not even see the algae but the pool walls or floor may feel slippery on your feet and then you will see what is called a full bloom where it turns green/greenish brown and it displays itself on the bottom and walls of the pool. Make sure to test your pool water and get your levels balanced and add your algaecide and I suggest letting the pool run until it is clear. You may have to chlorinate more as your free chlorine will be busy attacking the algae and will be harder to keep at the proper level until it is gone. After 24 hours vacuum the visible algae up (if you have a full bloom of it this may take more than one vacuuming as you will stir the dead algae up and will need to let particles not picked up by vacuum and filter system to settle and revacuum again).

What chemicals should we use to open pool?

Depending on your size pool, when you are first opening I would suggest using a couple gallons of liquid shock and a non foaming algaecide to start. These should be dispersed one at a time by walking around the perimeter of the pool while the pool filter is running. Let the filter run for 24-48hrs and then test your water for PH, Alkaline, Hardness and Cyanuric Acid. I usually tell my customers to wait the 24-48hrs so that if you have to do a lot of vacuuming hence backwashing you are not backwashing your money with the water so before adding a bunch of chemical try to do at least a good 1st vacuum.

Sand or DE is going into the pool?

This problem is usually a signal that there is an underlying problem with the inside of the filter system. With a sand filter check your elements and pipe assembly for cracks for DE filters check the fingers or grids for holes, cracked plates or parts, rigid gaskets even a missing shaft o ring could be the culprit. Both are hard to clean up once in the pool and take a good amount of brushing and vacuuming once the filter is 100% functional. If you have a cartridge filter check the pleats of the cartridge for tears.
Air in system?

Some quick tips is to check all your connections making sure they are tight, that all o-rings are present and good. Check your pump cover o-rings and gaskets a lot of times it is as simple as replacing these. If your filter system has an air relief valve let the air out through the system and retighten this may settle the issue. Check for cracked fittings, hoses and skimmers.

I have no flow of water coming into the pool?

Check your pressure gauge on the filter, this is usually a signal it is time to backwash your filter system. Remember to add DE if you have a DE filter. If you have a cartridge filter pull the cartridge out and wash completely (no soap). For spring pool openings you may have to do this a few times if the pool is full of algae, once the pool is clean backwashing during the season is a once or twice event.

I hooked up my filter and pump and my pump hums or does nothing?

Your impeller on the pump may have seized. With the pump UNPLUGGED try to see if you can turn the impeller free. Sometimes an acorn or small particle gets caught in there. If it doesn’t move and is frozen its may be time for a replacement motor. You do not need to purchase entire pump system, most of the time a replacement motor is your answer most local stores sell them, and if you are not handy they can also change them out for you.

My pump is leaking?

Again this maybe an easy fix and you maybe in need of a Seal Assembly about $10-20. If the pump is leaking at the housing part (where the basket sits) you can usually just purchase that part instead of an entire pump as well.

What type of salt should I use in my Salt Generator?

It is important to use only sodium chloride (NaCl) salt that is greater than 99% pure. This is common food quality or water softener salt and is usually available in 40-80 lb. bags labeled "Coarse Solar Salt". It is also acceptable to use water conditioning salt pellets, however, it will take longer for them to dissolve. Do not use rock salt, salt with yellow prussiate of soda, salt with anti-caking additives, or iodized salt.

I will post more questions as they come. Feel free to ask, I will get to you as quickly as possible.
