RODI alternative??

jammerdave · Sep 30, 2015

Is there an alternative to RODI water for top off and water change? I'm in California and we are in a drought. RO water uses huge amounts of water. My water bill is huge and I feel terrible wasting this much water. 20 gallons to make 1 gallon is crazy.

Mybe buy saltwater from lfs. Or there ro/di water. Check local water co. Mybe they have a free facet of RO and you run through Di.

Depending on your tds, you might get away with just di.

Agree, 20:1 seems out of whack.

You can set it up with another membrane so it runs the wastewater through again an makes it more efficient. I've not done this, but I've seen that setup. I'm sure seine here can tell you what to buy.
