Re: Green Water - Algae?
Will do.
If this is algae, I'm puzzled as to what happened. I opened the pool using liquid bleach and only switched to trichlor after the FC levels were established. I checked it at least once per day and it never got below 4 ppm. Mostly, it was in the 6 to 10 range. What am I missing?

There is another possibility. If the tablets had copper in them, copper can stain filters bluish green, and sometimes color the water. If you post a picture -- just supply the link -- to Flickr, Facebook, Webshots, whatever, I can probably tell the difference between algae and something else. If you use Facebook or some similar services remember to make the picture visible to the "world".

Here's the link. Took this a couple of hours ago.

DEFINITELY, algae!
Add 2 gallons of 8.25% bleach, tonight if possible.
Get cheap OTO kit and test chlorine following night. If OTO light yellow, add 2 more gallons; medium yellow, 1 gallon, DARK yellow to ORANGE, 1/2 gallon.
Continue dosing nightly until pool has no green!

Done.
Still at a loss to understand what happened. I have the Taylor K-2006 kit and have been testing daily (sometimes twice a day). I'm pretty certain that I've been doing the FC, CC, and CYA tests properly but I can't think of any other explanation for how algae could have started when I've maintained (or so I thought) pretty high chlorine levels all summer.

Re: Green Water - Algae?
It looks like mustard algae. On some pools, it seems to take root almost instantly, if you let chlorine levels drop. Once present, it doesn't die unless levels are VERY high.
It's difficult to eliminate, but fairly easy to control on vinyl pools -- moderately high chlorine plus careful brushing will eliminate 99% of it quickly. BUT . . . it's not gone, and will return at the first opportunity.
It only lives where nothing disturbs the surface it's on -- thus, it often begins on the side walls in the deep end.
