So I am going to be building a shed for a fish room. I plan to have a 360 gallon ray tank, four 40 breeders and a 55. I am still not sure what I am going to use to filter the 360. I am going to be building the shed with a barn roof because I want to have a loft to store supplies and I was thinking that I could maybe put an overhead sump in the loft. My main question is what should I use for the foundation? I still haven't decided on the final dimensions. I wanted to use pier blocks, but my dad says that we will never be able to level all of the blocks. My dad says that I should use concrete, but that sounds like a lot of work. What should I do?
