So i have a question.
My pool is an outdoor pool with metal-sides and a rubber bottom.
Over many weeks now i have maintained my pool every day. PH is 7,6 and Chlor is between 1,5 and 2. I use the phenol red and dpd1 tablets to Measure - and i measure every day and add chlor every day - to keep i close to 2.0 constantly. I add the chlor every night when pump starts.
every day i also vacuum the pool, so in the evening the pool stands razor Sharp. Totally clear water and no debree anywhere.
So at night it put on my summer cover and my pump runs for 8 hours (22:00 - 06:00) - and every morning i have several green/Brown spots on the bottom of my pool. I assume its algae because they are dust-like and easy to vacuum up with my catfish.
but why do they come - every night - when the pool is well balanced and its totally cleaned the evening before ?.. is it just How it is or is there something i Can do ?
