I have a 90 gallon tank that i will put discus in. i want to make it have a automatic water change system, that will pump in 15 gallons per day with a ro unit. and i will need an over flow system, but i do not want to drill the tank, so basically, it will pump water in with the ro unit, and will leave with an over flow. how can i do this? how do i set up an ro unit to do 15 gpd?
