wanareef Posted May 2, 2009 Share Posted May 2, 2009 Finally finished the RO/DI and saltwater mixing barrels. Have these two 55gal drums, one for collecting ro/di (on the right) and the other to mix the salt. When it's time for a WC, I can assemble the plumbing together, pump the ro/di water into the left barrel by way of a hose and ball valves. Once I have enough water, I add the salt thru a "port hole" in the top of the barrel, turn some valves and the Iwaki pump will mix the salt and water for me. I can add a heater thru the same opening to heat the water. By turning the ball valves, I can now pump the fresh saltwater to the sump to fill it back up. When I'm done I can stack the mixing barrel on top of the ro/di barrel ans still have it collecting water for the ATO. Of course this is borrowed from RC.

siskiou Posted May 4, 2009 Share Posted May 4, 2009 How far away from your tank are the barrels? I'd love to do something like that, but would have to do some fancy plumbing under the house, and that's just not going to happen. Quote Link to comment Share on other sites More sharing options...
wanareef Posted May 5, 2009 Author Share Posted May 5, 2009 With a Refractometer. There's a 6" flange and cover on each barrel to get into. The distance is about 20' and I plan on using a garden hose for the water changing. Quote Link to comment Share on other sites More sharing options...
