No chlorine

[Stingray]

Water Mom

The non chlorine shock had these ingredients:
Dupont Monopersulfate Compound …………………….. 85%
INERT INGREDIENTS: ……………………………………………….15%
TOTAL……………………………………………………………………….100%
The Chlorine shock has these:
Calcium Hypochlorite ......................68%
Other Ingredients ..........................32%

I purchased the jugs of bleach and the OTO kit.

According to the OTO kit my PH is 7.2 and Chlorine is 0 or .5.

What should I do with the jugs etc?

Thanks for helping me.

The reason you're having trouble keeping the pool algae free is because your stabilizer level is so high. If you'll take a look at the "best guess chlorine chart" link in Watermom's sig, you'll see that with a stabilizer level of over 100, you need to keep your chlorine levels between 8 and 15 ppm AT ALL TIMES to keep the pool clear. That's one of the pitfalls of using trichlor tabs--people don't realize that as the stabilizer levels rise, so must your minimum chlorine levels. So....stop using any form of stabilized chlorine, including the tabs, and use bleach to shock the pool. With a stabilizer level that high, you're going to need to take your chlorine up to 25 ppm and hold it there, by testing and adding more as many times a day as possible until the pool clears and you're no longer losing more than 1 ppm of chlorine when testing at night after sundown and again in the morning before the sun is on the pool. In a pool your size, each quart of 6% bleach will raise your Chlorine by 1 ppm, so you can use that as a guide to figure how much to add. When you get to the point that you're no longer losing chlorine overnight by testing as I explained above, then you can let the chlorine levels drift back down, but only to the 8-15 range...if you let it go below 8 ppm, you're inviting the algae back.

Keep the pump running 24/7, cleaning the filter as indicated by the pressure rise, and brush the pool daily.

Thanks for your help. Already today the water is clear and blue with plenty of chlorine.
