Quick update. I added a bit more water to the tank and covered all the rock with wet towels. I added three power heads to the tank for air and water flow. One is flowing water up onto the towels to keep the rock wet. Did all this yesterday.
Today I went to two Ace Hardware stores, Home Depot, Lowes, and a specialty plumbing store looking for the plastic flap style Check Valves. No luck; I'll have to order then online and wait, wait, wait. :(
I got home at about 9 pm tonight to fid all fish dead. And I mean all of them. My three clams, four brittle stars, crabs, anemone, sea apple, etc...
I think all the corals are pretty much gone. If something makes it it truly will be a miracle. This is far worse than my tank boil. This when all is said and done will be a total loss, I think.
On a positive note, I won't have to about anything when I go on vacation.
I took some pics of dead stuff but it's to sad to post. That's it for now.
