I have a 6 foot by 4 foot area in my fish room that I can house a sump I want to make it out of tote containers of some kind I was thinking of using three of them one for my skimmer that I have not purchased yet. The second for my refugium and the third for some live rock storeage an return pump I have a 75 gallon display tank that I am working on getting up soon just need some ideas on what size containers? What type name brand containers? And the setup for the setup for the three containers if this is a good idea. All help would be grateful thanks. Plumbing also.
