Water test results and proper levels

Postby Deniselcope2 » Tue 21 Aug, 2018 14:47

4' x 15' above ground pool.

I am at a loss, every time I try to balance this pool it goes totally wacked,

Free Chlorine - 10/20
pH. - 6.8
Total alkalinity. - 40
Hardiness. - 150
Cyanuric acid - 300

Please help I don't know what to do.

OK, you have lost already. To start, you need to drain and replace just over 4/5th's of your water to get the CYA to around 50ppm.

If your alkalinity stays around 40-60ppm that's fine, it's a vinyl pool you do not want it any higher if you want a very stable pH (you do).
The reduction in the CYA should also help your pH return to mid 7's.

Pop back when you have done it and we'll take another look. Using pucks for chlorination constantly has caused this, switch to bleach!

Get a decent test kit (taylor K2006c or TF100)
Stop using stabilised chlorine it has cyanuric acid and will reduce your pH and TA
You need to reduce your CYA as it renders your chlorine ineffective you need to get it down to about 50
The only way to reduce it is by draining and refill (what is your pool) if inground do you have a high water table
Use the following products to balance
Liquid chlorine (sodium hypochlorite or plain bleach)
Muriatic acid (hydrochloric acid) to lower pH and TA
Bicarbonate of soda to raise TA
Aeration will raise pH only
Soda ash will raise pH and TA

No need to waste water.

He can add bicarbonate or soda ash to increase the ph which will reduce cya and increase alkalinity and ph.

And yes no more pool tablets for shocking just use bleach or hydrochloric acid
