Ive been doing so well keeping algae away, but came home yesterday after work and bam..All over the floor of the pool....We had some heavy storms that rolled in yesterday morning, so im thinking its the culprit..Before I added anything, I checked my FC and it was at 7, and my cya is at 50.....Seems like a slam is in order...Good thing I havnt pool pool stairs back in yet, or would have a real mess on my hands..
