I just use 2 Brute trash cans. 1 for Top Off, and the other mixing salt, plumbed into sump. I have them located other side of wall in my office. Works good for me...
Thanks guys. Ya I'm pretty much planning on going with the Brutes. I've been all over CG and most if not all the 55 gallon drums are closed top so that won't work. I have a plan now though.
