Here is the story, last night I had the following numbers when I noticed what I thought was yellow algae:
I have 40k gallons. So I vacuumed the pool, brushed everything under the sun (well moon), and then dumped 7 pounds of dry acid in waited an hour or so, got the ph down to a nominal level, and then added 7 pounds of 73% hypocarbonate to start the SLAM process (shooting for about 18-20 FC). Pump was running all night.
Well I just woke up and the water is not only cloudy, but the floor has even MORE algae on it. Does that make any sense? Does algae grow faster at night or something? How can algae grow so quickly at these levels of FC?
