adrand Posted March 5, 2016 Report Share Posted March 5, 2016 I just got my first RODI filter in order to save myself from buying buckets of it at the lfs. I never realized how much waste water it produces. I know I can use some for watering plants and gardens but considering it is winter here in new england that wont be happening anytime soon. Does anyone use the waste water in non shrimp tanks? I have a planted tank with fish and some rcs culls that i currently use tap water in now. Was thinking i could use the waste water in that. The parameters of the waste water is tds 190 kh 2 and gh 5. Could i treat it with seachem safe and use it in that tank or am i missing something? Is it unsafe for the fish?

oem Posted March 5, 2016 Report Share Posted March 5, 2016 Since RO flushes the membrane backwards to clean, I'm guessing you will have higher concentrations of the minerals and other material being removed. I thing it would be fine for garden or indoor plants due to these extra goodies. Someone with more Aqua. experience should answer your tank question. ,,,,Mike Quote Link to comment Share on other sites More sharing options...
stangmus Posted March 5, 2016 Report Share Posted March 5, 2016 I save my waste water in a 55 gallon drum and use it for my African cichlid tanks. Quote Link to comment Share on other sites More sharing options...
Pescador Posted March 5, 2016 Report Share Posted March 5, 2016 I agree with OEM, as the waste water is carrying away the contaminates and minerals the RO membrane is rejecting. The waste water is passing through your pre-filters first so if they are new the water has had a lot removed before reaching the RO membrane. It is kind of a tradeoff as on one hand the waste water is pre-filtered thus better than tap, but then on the other you may have a higher concentration of the very fine contaminates that pass through the pre-filter but are rejected by the RO membrane. For me I use remineralized RO water for all my tanks, fish or shrimp and waste water is for my terrestrial plants. Quote Link to comment Share on other sites More sharing options...
Vpier Posted March 5, 2016 Report Share Posted March 5, 2016 I cant see why you cant use it for other purposes. It does have a higher concentration of minerals and some people call it "contaminates" but its not an unheathly contaminate. I think some will use it to mix for neos to get KH higher. wonder if you can use this for sulawesi shrimp? I have well water that goes through a softener first then rodi Quote Link to comment Share on other sites More sharing options...
Shrimple minded Posted March 5, 2016 Report Share Posted March 5, 2016 I was going to mention it earlier, but someone here uses their RO wastewater for Sulawesi..........I think it my be Taylor's Aqua World? Quote Link to comment Share on other sites More sharing options...
adrand Posted March 5, 2016 Author Report Share Posted March 5, 2016 Thanks everyone. Exactly what i was hoping to hear. I am definitely going to try it in that tank now. Once spring arrives i will also use it in my gardens but that is aways off. Quote Link to comment Share on other sites More sharing options...
