So with good intentions, I took the cover off the pool in May of this year. I then proceeded to never hookup the hoses and pump. What had been a reasonably clear opening quickly turned to a swamp. My thought is to dump 10 bags of shock into it, put the cover back on, and deal with it next season. But, i see talk on here of bleach?!? and with a 27' round with water up to the inlet (3'?), is there an actual quantity that makes sense? 10 of something is just a grab out of the air number.
Thanks for any advice/thoughts you might have. I will continue to browse around and have a beverage until I make a decision.
