I just finshed building a cool water change system I designed.It can pull fresh RO from my resevoir to my mixing container, recirculate the mixing container, drain old saltwater from my tank to the drain and pump the new saltwater to the display. All using only one pump, 7 ball valves, and a bunch of fittings. Whole setup including wood for frame and containers was about $90.(I got the pump used for $40, and I got the ball valves for 50 cents each online ) It works great its gonna make my life sooo much easier. If anyone wants pics or the plans let me know, I would be glad to post em if anyone is interested.
