I have other tanks setup like you describe and they work great! Can't beat simplicity and reliability. I wanted to do something very specific with mine and push some limits. Couldn't be happier with it but it's not for everyone.Yeah, I was thinking of doing the exact same thing and get the powdercoating. Read the rest of the thread...
