Hello,
I have a 120 gallon with 20 gallon sump tank that is set up as a mixed reef tank. I am currently doing weekly water changes at about 15 to 20 gallons a week. Everything is good but I have been thinking about simplifying the process and getting a DOS unit and set it up for auto water changes. I was thinking about 3 gallons a day for 5 days (15 gallons a week or 10% roughly), then 2 days off, then repeat. The 2 days off will allow for new water to be made and stabilized before going into the tank. The container holds about 30 gallons so I would only have to do this twice a month but for ease of programming do 5 on and 2 off. What do you guys think? Any downfalls to it? Will it be good for the tank? Thanks.
Rob
