So my plan was to put 4 75 gallon tanks ..... Bit then I got of track and was thinking about two 120 gallon cube tanks ..... With a 75 gallon filter on bottom ........ My question is if I do my first plan do you think I could do 4 75 gallon tanks and on 75 gallon filter ... The stand was build with the thought of holding a ford fusion !! Guidance please....
