Winter Closing

by Bob

I live in the Northeast, NY to be exact. I have an in ground pool about 17' X 33', eight foot deep at the deep end.


When closing the pool for the winter how far down do I have to drain the pool?

Must I drain it at all?

I'm asking this because I need a new cover and I'm trying to figure how big the cover must be.




Thanks for the question Bob

Normally most pool owners would drain the pool a few inches below the lowest return. This way they can be assured all the water is out of the lines and the skimmer.

Be sure to blow all the lines out with a Shop Vac or something similar. Plug up the return when you get a good stream of air bubbles.

I hope this has answered your question to your satisfaction.

Winter Chemical Levels

by Keith
(Georgia)

Do I need to maintain salt and cyanuric acid levels in the winter when chlorine generator is not running?




Thanks for the question Keith

Here's a question I recently answered about this very issue:

Cold Weather Question For A Salt Pool That Runs Year Round

The short answer is, while the pool chemicals are not as important in the Winter as opposed to the hot Summer months, it's still important to check the levels, at least every other week.

Sun and heat will eat up chemicals fast, so weekly testing is important in the Summer.

When I had my pool route in Arizona, a typical pool, 25,000 - 30,000 gallons, would go through 5 - 6 Trichlor tabs each week. In the Winter the same pool only went through 1 - 2.

So, while you may not have to add any chlorine tabs or salt, it's still important to check it. It's a "better safe than sorry" mindset.

I've always erred on the side of caution and encourage pool owners to do the same thing.

Pool Alkalinity And PH

by Riham Nasser
(PA, USA)

Our pool got plastered last week ( 20x45 ). We were told to test it everyday for 30 days before we close it. Today was my first time to test it , PH was really high and alkalinity was 130 ppm , I added a whole bucket of dry acid.

I was told to add sodium bicarbonate if alkalinity is lower that 80 ppm , but I wasnt told what to do if it is higher than 120 ppm.

Will this will be fixed by adjusting the PH by using the acid?

Thank you




Thanks for the question Riham

The acid you used to lower the pH may have affect on the alkalinity to some degree. Acid, as you know, is used to decrease both the pH and alkalinity. It just depends on how to add it to the pool.

To lower the pH you want to add the acid around the perimeter of the pool with the pump on and water circulating. Make the adjustment in the evening then retest in the morning. Make another adjustment if needed.

The question gave me the alkalinity reading but not the pH, so I can only guess what that could be.

Your alkalinity is not far off. Ideal is between 80 - 100, 120ppm being the top. If you're at 130ppm, just a small adjustment will be needed.

Pool Alkalinity

Total Alkalinity

The main thing to remember is to make adjustments one at a time, and slowly. If you put too much of any chemical into the pool you can overshoot your target. Then you have to make another adjustment to fix it.

Try to always add anything in the evening, then retest in the morning. This will give you the most accurate reading. If you add a chemical, then retest in a hour, you're not going to get a good reading. It takes one full turnover of the water, about 8 hours, before another test should be taken.

How Much Liquid Bleach In 3800 18x36 In Ground /Closing Pool

by Karen D
(Wayne NJ)

How many gallons of liquid bleach should I purchase before closing my in ground 18x36 pool? Vinyl liner.......chemicals have been neglected since we came back from vacation...pool hasn't been used.

Thank you.

Karen D




Thanks for the question Karen

Sodium hypo, or liquid chlorine, has about 15% active sodium hypo while bleach has about 6%. It's basically about 1/2 strength so you'll want to double the amount of bleach.

It's 1 1/3 qrts. of liquid chlorine to shock 5000 gallons. That would equal about 3.5 qrts. of bleach. I'd round that up to 1 gallon.

Be sure to sweep very well to loosen up any algae on the walls, keep the pump of FILTER, broadcast the bleach around the perimeter of the pool, then sweep again to mix.

If your objective is to clear up the pool you're going to need to balance the chemicals out and shock on a regular basis. Simply shocking the pool one time, and with the chemicals not being balanced, would be, in my estimation, a waste of time and money.

However, without knowing what your ultimate intention is and the chemical numbers, the direct answer to your question is 1 gallon of bleach.
