Above-ground Pool (10' x 30")..Simplest Maintenance

by G
(Malaysia)

I have an above-ground metal-framed pool. 10' diameter x 30" high and a secret for the simplest maintenance.


It is positioned on patio tiles & under a polycarbonate awning.

After filling with water, I add about 5kg of diluted table salt solution.

We use the pool daily for 5 days at 1.5hrs per time. I then fully drain the water, leaving the pool to dry for 2 days.

Thereafter repeat process of refilling, adding salt & using for 5 days.

Being in a tropical country, we get to enjoy the pool almost year-round except rainy season where it gets too cold to swim.

I have a swimming pool filter pump that came in the box, but as electricity is expensive, I don't use this.

This is how I maintain my pool water & it's clear, clean & chemical free.




Thanks for your comment G

Maybe others in similar climates can learn from your technique. I'd love to see a picture of what you've done with your swimming pool.

That's what make this site so good. Everyone contributes their successes and shares them so others can get the benefit as well.

Good luck with your pool and a have a great swimming season.

Newbie With Chemicals

by Linda Behrends
(Noblesville, Indiana)

I have a 15x48 4400 gallon pool. The pH is 8.4 the Free Chlorine is 0, the Total Alkalinity is 240, Stabilizer is 20-50. I am using AquaChek 15-sec pool test strips.

I am not quite sure how much Muriatic Acid I should add. I believe I should add 2 qt. tonight and test in the morning, and I should add 2 gallons of liquid chlorine.

Please Help




Thanks for the question Linda

First thing is to determine the exact amount of CYA you have. 20 - 50ppm is a big spread. At 20ppm you'll want to add Dichlor chlorine. This is stabilized and will increase both the chlorine and CYA. At 50ppm you're at the top of acceptable. By increasing the CYA the chlorine must also increase to keep the chlorine/CYA relationship. Once the CYA gets high, above 70 - 80ppm, a partial drain and refill is in order. The range for CYA is 30 - 50ppm.

Generally, you want to fix the pH and chlorine first. It's 6 oz. of muriatic acid per 5000 gallons to reduce the pH 0.2. The range for pH can be 7.2 - 7.8. Your current pH is 8.4 and you'll want to drop it to 7.6. That's a 0.8 decrease. This means you'll use 24oz. of muriatic acid broadcast around the perimeter of the pool with the pump on FILTER. Make the adjustment at night then retest in the morning. You'll want to check the TA as well because acid reduces both the TA and pH.

For the chlorine, it's 1 3/4 qrts. of liquid chlorine per 5000 gallons to shock the pool. What you can do is add the acid first, wait about 3 hours, then use chlorine. Never put one chemical on top of the other. Wait a few hours between applications.

I'd suggest getting a good test kit. I use and recommend the Taylor K-2006 or 2005 series.

Do these steps and remember to test morning and night until the chemicals are in range. And keep a log of times, dates, amounts, etc... so you can see any patterns developing.

Above Ground Pool Stained

by JILL
(MISSOURI)

WE HAVE HAD OUR ABOVE GROUND POOL FOR ABOUT 4YEARS NEVER HAD A PROBLEM UNTIL LAST YEAR.

WE HAD OUR WATER TESTED AND THE POOL PLACE SAID IT WAS FINE. IT WASN'T WE COULD NOT GET THE STAINS OUT SO OUR WATER IS NICE AND CLEAR BUT THE BOTTOM HAS THESE BLACK NASTY STAINS.

WHAT CAN I USE TO GET THEM OUT?




Thanks for the question Jill

Here's a good post with the exact same problem:

Vinyl Liner Has Dark Stains On Bottom

Before you begin any shock or algecide treatment, read that post first.

It basically says you need to figure out what kind of stain it is, either organic or metal, using Ascorbic acid (Vitamin C tablets) and pool chlorine tablets. More than likely it's not black algae. This kind of algae usually finds its way into plaster pools, not vinyl liners. It can, but highly unlikely.

The stain could possibly be a fungus and growing under the vinyl liner. To treat a fungus would mean getting a fungicide and putting that under the liner. Unfortunately this requires draining the pool, removing the liner and putting a fungicide down.

Look over the above post. There are also other links to good pages.
