Need help-High Cya, calcium, and algae

[Turbo]

30 ppm sounds like a good plan. I put in 10.5 gallons of 6% bleach last night at about 12. At 7 this morning it was all gone. Maybe it left so quick because I tried to scrub a section of the wall with ascorbic acid when the pool was low but I didn't think there was that much that stayed in the pool. Maybe so. I guess that combined with the algae did it. I put more chlorine in this morning (4.2 gallons which is all I had). I will buy some more on the way home and get the ppm up to 30. When will the chlorine level stop dropping so much?

Should I try some ph minus to get my TA down or just hope my little bit of aeration does the trick? I am going to buy a jet that will shoot the water in the air hopefully to improve my aeration ability.

Hi, Greg,

I would focus on the Cl level for now. Your TA is not at all dangerously high and I would "fine tune" that issue later.

You still have a bunch of organics in that pool and chlorine is your answer. Get a bunch of it and keep bringing it up to 30ppm as much as three times a day if you can. It may take a few days, but your Chlorine will start to hold more and more. Your water will be crystal clear and then you can start to fine tune that Alk.

PS - I believe it was the algae that ate your chlorine...not the acid.

I have no way of telling how high the CL is but I kept dumping in cl to keep it high for 3 days (before putting in 3.5 gallons each day of bleach it looked way darker than 5ppm). The water is clear and I put some 14 lbs. of dry acid in and have the TA down to 130ppm (put in 4 lbs. of borax to bring ph to 7.2). After the chlorine drops I will put in a little more and get it to about 100ppm.

Anyway, I noticed that the sides have a very light green granular looking growth over most of the pool and it won't scrub off. When I vacuum it looks like light green granular chlorine if that makes sense. Hopefully, it will decay and come off slowly. Any thoughts as to what this is and how I can remove it?
