i need some advice quickly, i have a very green pool after uncovering last week and not being able due to weather to get it up and running at that time. so today it is a big green mess and getting worse by the day.
we have storms for the next 2 days coming so i can not hook up the filter and pump until after that. my concern is, if i go ahead and get it hooked up and filled back up and running and get my bleach in it, how bad is it going to be for the sand filter system? also, should i replace my sand this year in the filter, got the pool in July of 2012, so it has only been 1 1/2 seasons.
