New pool here! It was filled for the first time on May 30th. The pool builder maintained it for the first 1.5 months, and I've been taking a stab at it for the past 20 days or so. I ordered the TF-100 and paid for the Pool Math app.
So far, I've been adding enough bleach to get me to a FC of 6, but I'm still trying to figure out how often to add more. When I test every 4 days, FC is at 1 or 0.5. Not good - I know.
Rained several inches on 8/7, so I drained some out on 8/8. FC was 0, so I added bleach to get up to FC 6 and tested 1 hour later. The result was FC of 6.
Rained about an inch the night of 8/10, so on 8/11 I tested, and the FC was now at 0.5. I added bleach at 7:30pm for the FC of 6 again, and decided to do the OCLT.
At 11:30am the next morning, (forgot to do it earlier but it was cloudy all morning) FC was 3.0 and CC was 0.5. Tested again at 6pm - FC was 1.5 and CC was 1.0.
Other info - I brushed and vacuumed about 2 weeks ago. The cartridge filter was cleaned about a month ago. Pump is on 4 hours/day, which is enough to theoretically filter the water twice.
Pool still looks beautiful! Water is very clear. Any idea what's going on?
