Ugh. Major sump leakage tonight. I noticed it after I had completely topped off the tank before bed. Then, 15 minutes later, the sump is about 3 gallons low. And there's water all over the floor.
It's now 12:15. NDB and I spent the last 3 hours completely draining the sump, then when the pump couldn't suck any more, bailing it out by hand, until there was only an inch of water left at the bottom. Then, since my tank was only going to get about half the flow it's supposed to have (minus the returns from the sump), we removed the six K3s and cleaned them all out so they'd perform as best as possible. Then I added a MaxiJet to each end of the tank -- one of them is used for water changes, the other to power my remote DSB/fuge. The DSB/fuge that was hooked up to the sump, and now has zero flow, it's basically just a 35 gallon tub sitting there stagnant. The MaxiJets don't have the protective baskets, so I'm terrified that I'll find a bunch of fish piled up at their bases tomorrow, stuck to them. But, that's a risk I have to take to get more flow in the tank.
NDB has tomorrow off -- he's supposed to dust off my old 20 gallon tank from the back patio, leak test it, and try to set it up. He'll have to remove the broken 55 gallon sump from below the tank first... And figure out how to replumb it all... What a pain in the ass.
