I want to fill 100+ Gallons of saltwater for a new tank but don't want to use the RODI unit since it wastes 3-5x of water and will take so long to make.
I agree, just buy an RO DI Unit. Won't you need more RO DI to top off every day and do water changes every week??? Also, its not a bad thing to always have a good amount of RODI water circulating in a bin just in case of an emergency.
