I have 3 Brutes. One for NSW, one for RODI, and one for waste water. Since there's no sink in the basement yet I've been rolling it out to the backyard and dumping it for years. The brutes are great, quick, and easy. That being said, if I had to purchase 4 right away, I'd probably foot the cost for the vertical storage tanks right up front instead. I have vertical storage tanks now but when I upgraded I tore down two other tanks I planned to keep running and the Brutes are still enough. But when I add my QT tanks and frag grow out tank, I am switching over to the vertical tanks.
