Thanks Dave. I have already ordered the Unicel filters from Amazon earlier this morning. I have an old OTO kit that I tried to use this morning as well as the FAS-DPD for your exact reasons. I diluted the pool water down with my well water (1 part pool to 9 parts well), but it is still reading off the color guage no matter what. The kit is 4 years old so I assume the drops may be bad. The FC was 23 ppm so if my dilution methodology is correct, I should have been reading somewhere between 2-3, which should have been in the middle of the kit range. I'll pick up another this weekend.

Thanks Watermom for the link. This may be easier than all the diluting anyway. It has always been hard for me to use those color charts. I never can decide what my "true" reading is.

So I guess I will just continue pouring the bleach to it. I thought I could eventually get it cleaned up, but when the filter started coming out clean after 12 hours of pumping and no more deposits on the bottom, I started worrying that I am not killing any more algae.
