30 Gallons? Your worried about 30 Gallons in a month (120G-160G waste water)? I do 30G a WEEK on my 75G/29G tanks. :rofl:
Edit: Oh ya, there is such thing as 0 Waste Water RO/DI units out there.
If you are that concerned why not add another membrane unit your current unit (ie the waste water goes through a 2nd membrane), this will reduce the waste quite a bit.
Indeed, I may. Unfortunately, I am a novice when it comes to this RO/DI unit and the units in general. An area, in which I must now conduct immediate additional research.![]()
Oh ya, one more complete system

And yes, I really do change out that much water.. too many years of over compesating for a under rated skimmer and I think I just have OCD about it. I have tried to reduce my water change amounts but it is a hard habit for me to break.
