cloudy water

[mrszaff]

hi, my pool is not green anymore and I have the metal stain under control. See my post "green water"
but Now we have a cloudy deep end. You can see the drain but its not clear as a bell.Probably dead algae?
here are my numbers

FC 7.2
CC .4
Ph 7.7
Alk 70
cya 80

should I add bleach or use the calcium hypochlorite powder shock again? or something else?

Test your water at night for chlorine, and again in the morning before the sun hits the pool. If you lose more than 1 ppm of chlorine, or if your CC is above 1.0, then you need to shock the pool and hold it until you're not losing chlorine at night. If you haven't lost more than 1 ppm of chlorine overnight, then it's probably just the dead algae that needs to be filtered out.

Do you have a working pressure gauge on your filter? Is the pressure rising as you run the pump? I've looked at the Pool chart, but don't see your info, unless I missed it--if you haven't already, can you take a few seconds and fill this out for us so we can give you better suggestions?

But, if you shock, the stains may come back. It is a vicious cycle. But, if you have overnight chlorine loss then you have something in your water that is brewing and you have to kill it. That is why once you get your metal/stain issues dealt with, it is critical that you always keep your chlorine in range for your CYA level (based on the Best Guess Chlorine Chart in my signature) so that algae can't get started.

If you do have algae brewing, you will have to kill it and then deal with the metals and stain issues again.

this morning my my FC is 6.6 and CC 0

The filter is on 24/7 , it is still slightly cloudy but water looks blue

I can brush brown particles off the walls and bottom, dead algae or metal , not sure?
how much more bleach to add?

[Watermom]

What was your chlorine loss overnight?

For reference, in your pool, each gallon (4 quarts) of 6% bleach will add about 3.2ppm of chlorine. Use that to help you determine doses of bleach to add. With a CYA of 80, you need to keep your chlorine between 5-10ppm ALL the time unless you are fighting something in the water. Then, your shock level will be 20ppm and in a pool with metals in the water, you really want to avoid shocking the pool if you can.

'it only decreased . 6 overnight but I just took another reading and it's down to 4.4 after a very hot 94 degree sunny day so I will add 2 gallons of bleach

after adiding more bleach, I'm convinced im in a vicious metal cycle, I added ascorbic acid to see if it helps and it did, my chlorine is down to 1.6 so is it safe to put in polyquot 60 and Metalfree now?
