Water system
I have a 90 gallon tank. How much water reserve should I have on hand? I really would like to have a water system built next to my tank, I am trying to find out how big should the drum's I need to buy should be?

are you trying to use this for you sump or an ato system..?

IMO buy two 30 gal brute garbage containers. One for ro/di water and one for mixed salt water. The one with salt water should have a small power head in it to keep constant circulation in it.
