Looking for your thoughts. I have an endless supply of RODI water w/0 TDS from work, my only limitation is transport in 5 gal buckets. I can move three (15 gal total) in my car basically a day. While this has worked well for my 13 gal reef tank with weekly water changes, in a year I plan on going 100+. I might need to put in an RODI system at home. So do I give up free water for the convenience and cost of making it at home? If so, do you recycle the waste RODI for things like watering plants or flower etc?

The fish are staring at me with hungry eyes.
I got an RODI when I got a 75 gallon tank. As for the waste I put it down the drain. Water is not scarce here and it comes from lake and goes to a river. You can use it for other stuff like plants. It is basically hard water.

You would have a hard time convincing me to give up free water! It sounds like you need a better system then hauling buckets around. Maybe a bigger containier that fits in your trunk and a pump?
Really, it’s a choice between cost vs convenience. With a 100 gallon tank, for day to day operations, I don’t see you really needing any more than 20 gallons a week... less than 10 gallons for top off water and 10 gallons for your weekly water changes with maybe another 5 or so gallons a month for mixing dosing solutions like 2 part. In your situation, the argument I see for having an RODI unit at home is for having the ability to make large volumes of water on demand in case of an emergency situation.
Great points. Getting a 100 gal plus a 40-50 gal sump up and running would take a lot of up front moving of water from work to home and major water changes early on. Once cycled and happy, I agree that 20-25 gals would be needed weekly and I could continue to supply that from Free work water. It really is about the cost of convenience.....
