Im thinking of getting a rodi unit so i don't have to buy water anymore for mixing salt for my reef tank but am running into install issues, another topic, but my question is this:

Can i use the waste water in my fw tropical community tank? I have read a lot on this with mixed opinions on this. It has your standard tropical fish & plants in it.

I may have to install the unit in my garage where i don't have a drain, was thinking of having the waste water go into a 5 gallon bucket and use the water for my fw, thoughts or issues with this?
 
The "waste" water from the RO/DI will gave higer KH and GH than tap water... But will be carbon filtered...

I would just use tap water for the FW tank, and the RO/DI water for mixing new salt water.
