I'm sure this has been discussed previously but I'm not sure how to structure the words to search for it, so I would appreciate being led by the hand to the right words or links.
In the past I've lowered the water level a lot - 50% - 90% - when the CYA level got too high. Since then, however, I've fought a long and hard battle against mustard algae and I don't want to put a rent sump pump back in the pool, so I instead want to lower the water level more often and by lower amounts 5% or 10%, maybe, multiple times, as needed. I can buy a reasonable sump pump, or this question, should I risk using the filter pump and with a garden hose attachment. It's slow, and it appears I risk losing prime as the skimmer basket apparently handles 90% of the water intake to the pump.
