Well i played around with my waterfall on Sunday. Monday night i worked rather late and notice the waterfall wasn't splashing much so I made a slight adjustment with the hose from the pump and the rocks it splashed on to. It was dark out so it was a little hard to see. Well Tuesday morning my pond was down about a foot! That is about 1000 gallons. I have been filling it the last few days and it is close to normal. Update on the fish. The goldfish all look happy, The Sanke... I haven't actually seen in 4 months but I can kind of see him. The kuahku looks like it's dead, but it did move to another spot from the other day. I think I'm better off with goldfish for some odd reason....
