Thanks to this forum, I have had no algae this year using the BBB system.
However: I have a couple of bottles of polyquat left from last year when the pool store was telling me to put in 8 oz every week as prevention. Does this make sense? Or should I expect never to need it as long as FC levels are adequate (adjusted for CYA)?
Pool store also wanted me to add 8 oz of Jack's Blue every week to prevent stains.
