Green Pool..Lots Of Chemicals, Metals & Algaecides

by George Johnson
(Butler, PA 16002)

Pool was nice and blue. When we didn't have any rain for a while, I added water and we have well water well. It started to get cloudy then went to germ. They say it was the metal in well water so I shocked it and nothing.

Then put metal out in it and nothing. I then put in stain prevented in it and nothing. Then algeacide 60 in it and nothing. pH was high also. So then I thought the sand might need changed did that and nothing.

I just don't know if I'm putting too much stuff in now so please help!!

Thanks for your question George

First, I'd like to have your complete chemicals readings:

Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness. It makes troubleshooting much easier and the process will go quicker. Without these all I'm doing is guessing at what the problems are.

When you put Metal Out in the pool, what was the expected outcome from your part? A metal sequestrant does not remove metal from pool water. It holds it in solution until it can get filtered. Then you backwash the metal out.

Because metal sequestrants break down over time and get filtered and backwashed out, you need to weekly dose your pool if you have high iron and copper.

Metal sequestrants that are based on HEDP, phosphonic acid or something similar are the most effective. Jack's Magic Blue, Purple, and Pink Pink Stuff, Metal Magic, Metal Free, & Metal Klear are very good. Be sure any algaecides you use don't have any metals or copper in them. You don't want to add to the problem. I'm not sure what is meant by "went to germ". How long did you wait before each application?

If you could clarify some things and answer the questions above, I'm sure I can help.
