About a week ago our water started to get a little cloudy, similar to what we battle with pollen earlier in the year. Typically I throw a skimmer sock on and after a few days all clears up. This time things seem to be so fine I can not get them out for anything. Fearing an algae bloom Thursday I decided to run a SLAM to see what would happen. CYA is about 35. PH is between 7.2-7.5. Typically keep FC around 4-5. Took FC up to 13 for two days. It really took almost nothing to keep the chlorine that high, which indicated it was not an algae problem. Saturday night things seemed to be clearing up, so I ran the dolphin over night. Sunday morning, as cloudy as can be again, with almost nothing in the filter of the dolphin. Pool filter looks as clean as when I cleaned it Thursday. Skimmer Sock is only catching typical bugs and the like, not clogged with particles as I would expect. Vacuumed through the filter and no change again. When things settled again I tried the pool blaster battery vac we have used for a quick touch up with a microfiber bag. You can literally see the dust blow right through the vac and cloud things up as you run it. I left the pool uncovered for the past 36 hours just so I could see the entire thing a little easier. Last night I did a FC loss test and we lost around .5 or less of FC over night. I will let FC drift back down to 5 now I guess. I doubled up the skimmer sock for kicks just to see. Any ideas at all? I have no idea where to go from here.
