recycle water change water

so ive been thinking for a while how much of a waste it is to just dump your water change water and i was thinking maybe of a way to recycle it, you may not get it back to 100% but what if you set up a fuge only tank and left water in until all nitrates/phosphates are used up? or what about running a tank seperate and place polypads in them to absorb nitrates/phosphates/etc?

any input, not sure if this would be more cost effective due to less money spent on salt and your water bill but is it an option to make the water recyclable?

 

and trace elements? What salt are you using? Switch to instant ocean and it may be cheap enough that you won't need to consider this tactic!

 

im not worried about the cost im just trying to start a discussion about it, could be a possibility for fish only systems or if you dose regularly

 

Could work for fish only, but reefs need added calcium etc in the salt mix, I think.

 

Maybe a softie tank as well

 

I use mine to water the lawn, roses. As long as you spread it out and not just dump it in one spot time after time, it will work just fine.

 

The salts don't affect the plants? Also wouldn't that affect the fertility of the soil?

 

There are people that claim to never or rarely do water changes - methods to grow the bacteria and remove n and p's, skimmers to remove that bacteria, added calcium/other suppliments.

After all, SPS tanks need to be impeccable. The water changes from that is more than sufficient for soft corals and then on down to fish.

The extra work of maintaining all the extra tanks is probably the part that's not worth it.

 

Not with the quantities I am using, I am talking 15 gallons a week or so over 1/4 acre of lawn/plants. And I am not putting it in the same place twice.

 

Its a nice thought. Imagine being able to re cycle water. Wonder if running it through a ro/di would work. Would it remove the salt to? Guess you'd be back to adding salt mix, might help the water bill though. And of course you'd have to have a spare ro/di and pump for pressure. The genius that solves this will make a killing.
