Last Sunday(7/6) I lost my pump - had to overnight a new one. I kept adding bleach and manually mixing the water but obviously no filter. Pump was back online Tuesday (7/8) of last week. Friday (7/11)it looked like algae had started so I started slamming. I tested my CYA to be 60 (TF-100 test kit) so was shooting for a FC of 25. Starting Friday night at 8pm, it has been FC 25+ with the pump running 20-ish hours a day - on high. From the initial dose, it passed the overnight chlorine test the first day...odd...but very cloudy so I kept at it. Before I get any lectures, I cannot vacuum to waste - it would drain my pool and I might as well do a drain-refill at that point. I always backwash the pump after I vacuum. It is very cloudy still and I can see what looks like algae on the bottom after 24 hours. It is very hard to vacuum. Passing the vacuum head over the spots does nothing...more of a scrubbing than a nice "vacuum". Pretty much just stirring things up and makes it cloudier. Not sure how anything could survive FC levels of 25+ for 72 hours, but it is definitely not getting better. At this point I'm starting to think I have some filter issue since running the pump isn't helping the cloudiness. It is a sand filter, so maybe I should add some DE? Should I break down and get some pool store algaecide? Went to local pool store to get a SMALL box of DE and/or skimmer sock....they carry neither. Not sure what to do, but the family is losing faith in the TFP method....a mutiny is brewing!! here are my current test results.
Note -After the pump was back in action, I was trying to raise pH with Borax....Added one box over 30 hours...didn't seem to help much but the pool calculator said I needed quite a bit. I'm not sure if it had any negative effect, but I've stopped trying to tweak the pH (and TA) until I get the water to clear up.
