Hey guys, I am currently running a 75 gallon tank on just a canister filter on my first floor. I am planning on adding a fish room in my basement pretty soon and putting a sump down there for the 75 gallon and any other tanks I get in the future. I do not plan on getting rid of the 75 gallon, only adding tanks to that system - so i will be using a 150 gal rubbermaid tub as my sump, as well as a 40 breeder or a 55 as my fuge. Plan is to have the water go into the fuge and then gravity drain from the fuge to the sump. Problem is, fuge would be before any mechanical filtration so I do not know if that will cause any problems with detritus, etc. Additionally, was hoping to use the fuge to host copepods with the plan of eventually adding a mandarin dragonet so idk if that will work. Also, how would you guys recommend plumbing with the purpose of adding any future tanks. Since any new tanks would be in the basement, where the fish room is located, the plan was to have the water drain from the 75 into the 1 or two tanks in the basement and then drain from there to the fuge. Additionally, would only have one return pump pumping water into the 75. Could I do it so that the 75 drains into the new tank and then that tank just drains into the same plumbing just further down? I just want to future proof the plumbing so that it makes it as easy as possible when I do set up tanks in the basement in the future
