i don't want to take all the water and fish out of my tank it's a 90 gallon with no center brace I've asked before different questions but I'm wondering if I found a solution could I empty it to about a qrt full and cut out a 4" section in the middle of the top frame on both sides and silicone a 4" piece of glass on top of glass and just have that section of frame missing while fish and water are in it?
