Hello all. Just some more update on the this 180 gallon build. So as know I put water in the DT and tested it for leaks as well as it being leveled. Well i did just that and things went great. just head a couple spot under that had a couple of drips. Nothing to be really concerned with. I drained the tank today and and I couldn't get all of the water. Has a little bit on the bottom of tank. Do u think from this pic. Should I be concerned about leaving g it in tank. It's only a little right?
