keenfish75 Posted January 22 Report Share Posted January 22 Wondering if a RO setup would be enough to recycle/filter syphoned aquarium water and back into fishtank to save on water usage? Anyone doing this or similar or can it not be done? Link to comment Share on other sites More sharing options...
billfish Posted January 23 Report Share Posted January 23 How much water are you planning on trying to reuse? You still will lose 3 out of 4 litres trying it, trying to make something like a bog filter with plants that rip into the nitrates would probably work better, or something like a refuguim keenfish75 1 Link to comment Share on other sites More sharing options...

MFF Posted January 23 Report Share Posted January 23 I think the point @billfish is making, is that an RO system does NOT recover 100% of the water going in. At the very least 50%, and up to 75% of the water going in is diverted to waste, so that you'd only recover 50% or 25% of the water to re-use. The way RO systems work is by concentrating all the nasties into the waste water stream - the nasties have to go somewhere, right? This leaves a fraction only of the input water available for re-use. So you'd still need 50% or possibly 75% of the water fresh from the tap, reducing very significantly the appeal of the idea.

aquaholic99 Posted January 24 Report Share Posted January 24 Yes our town water is extremely cheap for such a high quality clean safe product. Even the tier 2 price is very affordable if you blow through your quarterly tier 1 allocation. You can easily and cheaply reduce your water consumption by slowing or removing your nitrate levels as well. A rain water tank sized to your needs for example. Or circulate your tank(s) through your IBC's filled with bog or aquatic plants. Can put a planted IBC outside as well, water turn over does not need to be high. Turn off water circulation for winter if you have tropical fish. I actually go the other way and culture green water with outside IBC's on rotation to boost colour ' provide live food to my fish room but as this doesn't reduce nitrate I won't derail. I collect and re-use some of my fish room waste water with a turtle pond down hill. The pond is used as a collection sump and I pump water out to an elevated rainwater tank which waters and fertilises the garden by gravity. johnbetta and keenfish75 1 1 Link to comment Share on other sites More sharing options...
