I am putting together a 320 gallon peninsula build, would like to get most of my small fish room done. I have (3) 60 gallon round drums that I would like to place under the landing of some adjoining stairs. The problem is that I would like to be able to use the valves from the next room so as I get older I don't have to crawl around on the floor turning valves. I have an access door the height of the drums so that I can add salt to the first drum for mixing, second drum for mixing, and the third drum for storing the premixed salt water.
