Green pool- depressed spirit

[chem geek]

In the future, when lowering FC to make metal stain treatments (e.g. ascorbic acid) more effective, you might try adding some PolyQuat 60 first. This will certainly keep away the algae at low or even zero FC levels. I don't know, however, if it will affect the metal stain treatment, but my guess is that it wouldn't.

IKnow I should have more POP but I seem to be all out of it- Just tested again FC is at 22 CC 0 Pool still green & cloudy- I vaccummed this afternoon and I intend to run the pump for the 4th night in a row and get my chlorine to about 25 to leave for the night-

Could this be anything else- or does algae just take this long to clear?

Yes, it takes that long. Keep the filter running 24/7. Make sure the filter medium is cleaned out also. Backwash if sand or DE, and clean off cartidges. My green swamp 2 years ago took a full week to clear. Be patient.

Polyquat will not affect the ascorbic acid, but it is too late for use in a green pool. ivyleager is right! You have to keep backwashing and brush the pool often. Vacuum at least once a day. Keep the filter running 24/7. You can also put a skimmer sock on the skimmer (or a cut leg of pantyhose) to catch some of the dead algae. It will clear
