OK, one more question please. We had some pretty good rains in the Houston area last week and although I could swear I kept my clorine level up I still ended up with algae. I've been shocking for 3 days and my test last night showed 19.5 and this morning it showed the same with no CC. Does that mean the algae is dead now and it just needs to get filtered out? If that's the case, should I add some clarifier maybe? I have some of the Leslies clarifier if I need to use it. My CYA was around 45 before the rains so I need to have it tested again, and I do keep one puck in the floater all the time. I find with backwashing and splash out this has kept my CYA level pretty solid all summer.
Thanks for all the great info,
