I just finished clearing out a mustard algae bloom. I ran the FC up to 30 (my CYA is 50) for about 4-5 days. According to the instructions in pool school, I have to wait for clear water, overnight FC loss of 1 or less, and CC less than .5, right? Last night my FC loss was 1 (7.5 to 6.5) and my CC's have been running .5 pretty much the whole time. This morning it was probably more like .25 because it was just the slightest shade of pink and I've seen it be darker before and 1 drop clear it. Anyway, the water looks clear from poolside, and I thought I was homefree, but yesterday when I got in to do a very thorough hand vacuuming, it looks very cloudy when you go under. I can't see the other side of the pool. It was actually pretty shocking to see it look so cloudy because it looks clear from the top.
So I guess my long winded question is....based on the other 2 parameters of clearing an algae bloom, do you think it's safe to return to normal FC levels? Do you think the cloudiness is just dead algae that needs to finish filtering out? or is "clear water" judged from inside looking at it with a mask?
TA 110
pH 7.8 (do I need to bring this down?)
17,500 gal above ground oval
TF100 kit, BBB method
2 speed 2.5 HP waterway pump & cartridge filter
Thanks in advance,
