This weekend was a huge buildup to setting up my reef. It was a real project, I had two pumps, a network of PVC pipes going everywhere, the tank on the stand and the other tank (the one that holds equipment and the like) underneath in the stand and I had everything ready. I did a test run to check for leaks and I had a few. I tightened those down, put teflon tape on a few connections, and tried again. No leaks. I was getting seriously excited. So I added a bunch of salt, got the salinity right, and then began to add sand and rock.
At this point paranoia got the best of me and I checked the back of the tank again to make sure that with the pumps running I still didn't have any leaks and that all my fixes were holding.
They were, but there was still water. Huh? How could that be? I saw water down near the lip of the tank, but my angle prevented me from seeing the crack at that time. I just figured I had spilled some water while putting rocks in. Then I looked back a second time, noticed more water, and decided it had to be coming from somewhere. But still, there was no visible source, no pipe sticking out, no pipe overhead, nothing.
Then I saw the crack.
Luckily I got everything out before the crack got so bad that it didn't hold water but man... This bites.
I don't have time to re-do it for another few weeks. I keep having family obligations down in Salt Lake (I know I want to see family and everything, but sometimes I just want to be left alone) and so weekends are eaten up with being down there.
