it most likely what your placing the tank on. I have a 20gL and when i placed it on one corner of my dresser the water level moves lower in the left handed corner. I placed it in the center and it leveled out. My 10g was in that same corner and had the same problem it was there for about as long as i have had this account nothing happened to it
no when i said under tank i ment under the entire stand, sorry.
so if i get a piece of plywood thats 36in x 18in (the amount of room in the corner) and put the under ALL the legs will this work? it seems it would work best because it would spread the wieght out a lot better than poles sticking into the ground
