I think I'm still okay on the p.h. as it never went below 7. I just have not read anything about adding way too much like I did. I like your tub with holes idea, I'll try it with many other desperate attemps tomorrow. If you don't know what I mean by mud pots, they are similar to bottom drains on pools: one suction covered by a lid with slits all around the edges so no one can get their guts sucked out. Each pump has two in the slime chance that someone could cover all those holes at once. There are six of those, two for each of three pumps, that is where the leaf baskets with the aquarium filler are.
I'm thinking maybe I could take one of those lids off and retro fit it to a pool size cleaning hose with a leaf basket in the middle and fill that with a lot of aquarium mesh stuff. To try to catch it with some suction behind it.
Thanks for responding.
