OK.

Its been 48 hours of non-stop filtering, and shocking per Ben's instruction.

I CAN SEE THE BOTTOM!!!!! Still hazy/light cloudy.

Not sure what is in the pool but its eating chlorine like crazy. I have been testing with diluted sample. 1/4 pool to 3/4 RO water. I know its not accurate but that all I have.

I would shock to over 15 ppm and in an hour or so it was at a 12 ppm. Sometimes 8 ppm. I just kept using the calculator and adding what it said.

Now since the filter was not doing anything before, I figure whatever was not filterable, becomes filterable from shocking???? Is this correct????? So If someone had a cloudy pool its shock thats important to make the material filterable? If so how? Isnt live algae the same size as dead algae?

OK so thats where I am at. The other thing is I am not sure what my CYA is anymore. No one sells it in NJ from what I can see. I dont think they are suppling it. Only online.

I bought the DPD powder, and R- 0871 reagent for chlorine testing from taylor. It was as cheap or cheaper then any online store I could find. I also bought some CYA R-0013.

Anyone know of cheap online stores they used?

I guess I will shock alittle higher like I did last night and keep filtering.

Ohh, had a heck of a rain storm last night with hail. I wonder is it helped the pool....LOL. After the rain is when it started clearing.. Might be coinsidence.

Next question is what filter should I run for best clarity??? I have a cart and sand. I am starting to think sand with DE added is superior to the cart. My problem is a 1 hp two speed pump. Its rated for the cart at 80 gpm. The sand filter is rated at 25 gpm. Whats this all mean???

After all these yrs I thought I knew what I was doing.
