Persistent green water

[PoolDoc]

I made a copy of your post, answered the 'greenpooltips' question, and put that post in the Hall of Shame, here:

There are about a bazillion posts about liquid chlorine or bleach here, so we have no idea what you read. I can't comment on the ZeoSand, except to say the more I know about the alternatives to sand, the less I like them. I can also add that, if your filter is performing more poorly than it has in the past, it's always a good idea to check it.

And . . . the "liquid chlorine treatment" is nothing more or less than adequate chlorination. The only difference between using liquid chlorine, and dichlor or cal hypo . . . is the OTHER stuff added to the pool, besides chlorine.

Finally, until you know your stabilizer level, you do NOT know what level of chlorine is adequate. Furthermore, if your stabilizer level is 60 ppm or more, you can't measure an "adequate level" of chlorine, without a DPD-FAS test kit, which for practical purposes means, without a Taylor K-2006 kit.

Read the Best Guess page in my signature, and then take a look at the Amazon links page for Taylor kits. You can order elsewhere if you like, but you'll need one from somewhere. A K-2005 is NOT an adequate alternative.
