Thanks for the replys.
The tank will be in my daughters room on the second floor and my RO/DI unit and holding tank is in the basement. I wasn't looking forward to dragging water two stories with a touchy knee if I didn't have to. This is why I have a nano reef, only small buckets of water for weekly water changes. Does anyone think a phosban reactor is required? I'm mostly concerned about algae issues. Thx.
