Okay I have my 75 gallon set up and cycling but I need to know something. Right now i have it so that it is parallel with the floor support boards. Should I move it so that its going across more boards or no?
it should be fine as long as you dont have a very old house over 150 gallons then start to worry,but if its bothering you just move it better now then later when you get fish
well thats not very old, does the floor move or creek when you walk on it,do you have a good reason to worry about the weight? it should be just fine,I have a 240 in an older house than yours, but I did suport the floor,cause I couldnt sleep at night lol
