Hello to all! I have inherited a swamp err I mean swampy pool. We're talking green and nasty. Pool was not used in several years but all things mechanical seem to be working fine. I am trying to clean and clear this pool for use but to little avail. I am testing with a Taylor FAS_DPD test kit (K2006). I am having a heck of a time with ph. FC-.2, TA-90, CH-180, CYA between 30-40. Ph maintained a relative constant at 7.2-7.4 for a long while but now it has spiked. I was preparing to slam the pool but cant get ph to lower. Began the week, my first reading of the ph was 8.0(or higher). I added dry acid per Taylor acid demand test and continued to retest. After several days and 19lbs of dry acid I re-tested the ph in the morning and came back with a 7.6 reading. Great!!!!! I prepared to slam pool that evening and retested the ph prior to the slam and it read 8.0 (or higher)????? Help, I cant seem to grasp why. Nothing has been added to the pool other than ph lowering chem's, and nothing at all the day I prepped to slam. the poo.l Water is 86-88 degrees and full algae bloom. I'm not sure what to do now?
