We purchased a new home in October 2015 and therefore, inherited an above ground (12K gallon) swimming pool. We were informed by the previous owner that he had already winterized it and no longer covered it for winter due to the fact that he saw no difference in chemicals required for startup, come summertime. Our pool was swampy green. We followed advice we received and super-shocked it, not realizing just how much debris had accumulated at the bottom of the pool. We have spent days scooping it out, have vacuumed, etc. We are trying to balance our water now that we have finally gotten rid of the "green." It is a very cloudy blue. We have shocked it and shocked it in the process trying to kill all of the algae that was present. Now, our chlorine levels are off the charts high, but everything else is in range. We put in a pool clarifier last night and still no difference. Why can't I see the bottom of the pool?! This is beyond frustrating! Any advice at all here is appreciated! Please and thank you so much!!
