I tried the stuff last October. I had CYA in the 180+ range. Got the pool set up as per the instructions and had 3 days of nearly perfect weather. On the fourth day, as it often does here in N. Texas, temp rose to 90 and (ka-blam) algae outbreak. Slammed pool, remeasured CYA and it was 140 or so....so the goo didn't have as long as it was supposed to to have maximum effect. So, don't know if it was worth the dough. Shortly thereafter I drained and refilled a bit more than half the pool and the result was a CYA around 70. Switched to a SWCG this Spring, so no more CYA probs......
