I went the drain, scrub, refill route. I couldn’t justify continuing to try to treat 2300 gallons of unwilling water. I’m 2 1/2 weeks and with out any results.
I drained the pool, scrubbed it with a very dilute solution of bleach, took the lights out of the niches and there was absolutely nothing that came out. I took the drain covers off and they were pristine, as well as the PVC pipe it was covering. No hints of algae anywhere.
My filters were washed with the TSP solution yesterday and they are in the filter cartridge.
Any out of the box ideas? Is this non-algae biofilm coating my plumbing? Is it possible I need to do some sort of hot tub (Ahhsome) treatment as well?
I pray this is the end…
