So here's my water station idea. Weekend project. I'm gonna pick up one of these and see if it will hold 20 gallons of water safely. Than I'm gonna try and put a bulkhead in the front down low. I want to build a shelf that will hold 3 of these brute trash cans side by side. Rodi, kalk, saltwater. Kalk and salt have bulkheads with ball valve drains. I want to be able to fill my 5 gallon jugs easily from the drains. Since I have to move the water upstairs. I'll put a pump in the first one get fresh Rodi into the mixing stations. Mixing ones will have my old koralia ' s in them to mix salt or the kalk. Sounds like a good plan if the brutes are sturdy enough!
