HI, thanks for the post.
I like it overall but if I were to do it again I'd get a bigger one to have more room for the bean animal plumbing. I couldn't get it to work out with the plumbing I had on hand so I am just doing a herbie style with an extra emergency drain.
I also have a very small leak from one of the holes (between the tank and exterior box) but that could probably be fixed if I tightened the bulkhead more. I'm just worried and it's such a small leak (seriously like 1 drop a week) thay I'm not gonna risk cracking my tank to fix it. The bulkhead is as tight as I can get it by hand. I don't think it's necessarily a problem with the box it's probably more a result of my drilling measurements or lack of arm strength.
Finally, the lid on the interior box won't sit correctly. It was fine before I installed it, and after it was on the tabk the lid just won't sit properly. I just put it on at a slight angle. I'm not sure what caused this, I can't figure it out.
