YAY! Finally leak free. Thanks to Whatcaneyedo again, got another bulkhead from him tonight and slapped it in. Fixed the piping and once dry let er rip.
Please excuse the smegglies from cutting the plumbing to fix up the overflow. Will drain, give everything a wipe down and should taste salty tomorrow. All I can say is I think I have a herbie overflow now because this is the quietest tank Ive had in a long time, since freshwater with no overflow really. No bubbles getting thrown into the sump either. Thats nice and huge for keeping the microbubbles down till I get the filter socks (the tank is running in the pic you see of the sump) . Hoping to throw the rock in it tomorrow and get the structure built up. Oh and I realize the plug behind the tank is not GFCI but will be changed over tomorrow before the tank is set in its final place. I have a sealed plywood back for it to seperate the tank from the drywall.
