I've seen those big Arm and Hammer boxes and I can easily see how that can happen. The HE bleach I was reffering to says "Great Value Rain scent bleach" and that's all, no info on the percentage of chlorine or anything else. I think it came from the grocery store my wife shops at (Publix). I'll check at Walmart and read their bleach. It seems to me that the local pool supply I've been dealing with cycles through their liquid chlorine supply pretty fast, they have it in what I would guess is about a 400 gallon poly tank outside and every time I go there, they are reffilling the containers and have customers lined up swapping their emptys.

I bought 15 gallons on this last Thursday and a new bucket of trichlor tabs. I dumped the 15 gallons in the skimmer Thursday evening and Friday morning the entire pool was sparkling, I checked FC Saturday morning and it was around 3.5 or maybe 4. I then put 3 tabs in the feeder Sat. evening and turned it on full. I just checked the FC again (Monday PM) and it's now about 1.0 and I'm seeing a very small amount of green trying to show only on the white steps in the diamond shaped recesses. So I'm not sure why that is already trying to come back, I'll check it again tomorrow and post the results. And I'll go get the CYA checked again.

Also on Saturday, I vacuumed a little bit that I had missed, no green just a little debri and then the water when from crystal clear to a little cloudy white and it still is. I've been running the pump nonstop and have cleaned the filter but it still very hard to see the bottom drain that's about 9 feet down.

Should I get some clarifier or what else is recommended ?

Thanks very much !
