*SIGH* Looks Like I Have da' Mustard

Honestly, I don't know. I *think* it mostly filters.

What puzzled me about using the Kem-Tek product was that I never saw any cloudiness, or particles -- but the PO4 level did come down. However, I was separating dosing and testing by a week or more.

I used 32oz. yesterday. I will wait and possibly do it again mid-week.

FYI--- Water is AMAZINGLY clear! I brushed the pool today and there were zero signs of algae. So far... so good.

Sounds good!

Any ideas on how long I should keep the FC level this high?

Normally, I suggest keeping it elevated a day or 2 AFTER all traces of algae are gone.

Hmmm... Very non-specific ;-) How do I know when ALL TRACES of algae are gone? I have to say that it has felt gone before and it came back again... and again... and again... and... well, you get the picture. It appears that most, if not all of it SEEMS to be gone. So maybe I will keep high until next weekend, then slowly let it drop to it's Best Guess level.

In other words: Nuke the site from orbit. It's the only way to be sure. :-D
