The OP is talking about a 180g tank (let's assume for the sake of argument that the total system water is 200g). If they change out 2g a day they are doing about 60g a month, for a total of 30% water volume. If they did it all at once every month it would reduce nitrates (and any other accumulated pollution) by 30%. By changing 2g a day it is reduced by about 26% (per the RHF article). There has been a 4% waste, in this case 8g. I don't see 8g of saltwater a month lost to be that big of a waste to gain the benefit of automating the process (plus stability benefits, plus not having to heat the new water). I don't mean to derail this thread, just wanted the OP to hear that I thought the plan for using the DOS to change 2g a day was a good one (IMHO).
