This is a great site, I've been reading posts for a while, but now I need some help. I don't have all my numbers from this morning, but hopefully I can get some help without that info. my CYA is 30 so i'm shocking to 12 per the charts I've seen while reading the forum.
I'm currently fighting a deep green algae mess, 0 visibility, can't even see the bottom of the 3' shallow end. Yesterday I skimmed the leaves off the surface and vacuumed as best as I could since I can't see the bottom. I removed all the grids from the DE filter and hosed all the gunk off the them, I got them as clean as possible with the water hose and reassembled the system. I then recharged the DE grids with FiberClear (I started using FiberClear last summer instead of DE, seemed a bit better in my pool). The normal pressure in the filter after all this is 15psi. I came back an hour and a half later and the pressure in the filter was at 30psi. I did the backwash/rinse/backwash cycles to clean the filter, recharged it and it was back down to 15 psi. I came back to check on everything a couple of hours later, the pressure was once again 30 psi.
It seems the filter is doing what it's supposed to, but that seems like a lot of backwashing, and a waste of FiberClear (or DE) which can get expensive. Could something be wrong (or user error?) it is a deep green mess, but the build up in the filter after a short time seems excessive. Is there a better way to handle this situation? I have a MPV and i thought about just using the 'recirculate' setting to bypass the filter and just get the the chlorine moving, but eventually I'll have to filter the dead algae. I've also read on here about nylons or skimmer socks, would something like that help in this case or will it just clog my skimmer intake?
