im sure if its the water its self is hard to get, then it may be worth the expence running it threw a ro filter. if you run it threw an ro its got to come back out pure again so its like starting from scratch. but remember you will still loose some of the water as waste so it might only be worth it on huge water changes if water is very hard to get hold of.

You won't just lose some of the water sending waste water through an R/O unit, you'll lose upwards of 80% to the sewer depending on temperature. The water return wouldn't justify the filters and membrane replacements. The only way to recover most of the water from the waste is too expensive and involved. You'd have to distill it out. Boiling the water and cooling it within a condenser to get distilled water without the waste. On a large scale (to justify the power costs of heating the water), you have to incorporate a cyclonic separator to remove the solids from the water column that impede the boiling.

I recommend not trying to save the water. Plant some nice veggies for your herbivores and use the wastewater in the garden. The amount of water you're dealing wiith, with those size tanks, on a weekly water change doesn't even add up to the amount you use to flush your toilet in a day.

out here in the desert where i live, [fabulous Las Vegas] water usage is expected to be used wisley. we are on a watering schedule. only allowed one day per week in the winter. i use the 60gallons out of my tank to water the lawn. wish i could put back in the tank. at least im not wasting though . good question..

This is the same city that uses mist cooling systems and huge fountains right? lol

I have read about a local aquaculture farm(that grows Murray Cod!), which is runninig a trial with a local university, using hydroponics along side the aquaculture to help sustain the water quality. Basically they run the water though a hydroponics system which grows lettuce etc. The hydroponic plants remove the nitrates and other waste products which the plants use and then it goes back into the fish tanks. Apparently its was working well last I heard.

The point? You may be better off trying to remove nitrates and retain the water longer than trying to reuse the waste water?

i might try to make a filter like that

Great info with alternative uses for the RO waste water. I have been considering getting a unit when I become a home owner, but have been hesitant due to the amount "used". I blindly figured that the water would be bunk in regards to gardening and house plants, just cause well, its the "waste" water. If it is indeed beneficial, it is almost a given that I will invest in a RO unit in the future.
