I have a ro/di that fills 3 44gallons plumbed brute cans. (Ro/di because iowa has horrible water from ag runoff) I add baking soda every couple days with some seachem remineralizer. From there an apex runs very hour to deliver around 15% w/c daily via masterflex pump to my tanks. A sump bulkhead exits to the floor drain. Two custom tanks are on this system (120 and 180) and plumbed together.
I don't spend any time on the daily water exchange. Generally on the weekend I will siphon out any crud on the bottom if there is any but the masterflex fills tank back up so it's just a 5g bucket and dump it out.
So total maybe 5 min a week or less.
