Had a pool party last Saturday with lots of people in the pool. Probably about 15 adults for a couple of hours. Then we had a very hard and long rain on Monday morning. I noticed on Tuesday that there was yellow powder on the floor which brushed up into a cloud like pollen has done in the past.
Before and after the pool party I had been maintaining 4% chlorine and CYA 30. Combined chlorine is always and still is less than 0.5 ppm. Sometimes doesn't turn back pink when adding the 5 drops of R-0003. This morning FC was 5 ppm and combined 0.5 with one drop of R-0871 turning the sample back clear. I've been running the pump 24/7 and put in some skimmer socks this morning to try to catch some of the pollen but they don't seem to be catching anything so I am wondering if I have green or mustard algae since the pool is green now and can barely see the drains 10 feet down. There was more yellow stuff on the floor this morning that could be brushed up.
Tonight I'm going to do an OCLT and find out for sure but always thought that if I had algae CC would be higher. Or should I start the SLAM tonight? Any thoughts on the CC question? Thanks!
