hello friends, im stumped and am turning as usual to the BBB guru's
2 months ago i got caught with low chlorine on several hot days. About a week later sediment started appearing on the floor of my pool. i swept, shocked, passed the OLCT and water cleared right up. 4 or 5 days later it started again. so again i did the standard ops, pool cleared up passed the OLCT. This time I stayed above 14 FC for several extra days to be sure. i removed the steps and scrubbed them as well. The moment my FC goes below 10 or so the sediment starts appearing on the floor of the pool. Quite frankly Im stumped and have considered the "pool store" for assistance. Ive read up on mustard algae but cannot determine if thats the problem.
Ive included a few pics of what my pool looks like after a few days. the only thing i can imagine is the algae is living inside the cartridge filter ?
