My house is an older house that Im renting. It is possible it may be slightly un-level. Ive never checked but It wasn't something that I noticed when I filled up the tank. (the water being not level)
If it isn't completely level, what can I do?
First, don't worry about it until you can verify that the tank's support is not actually level.
Buy or borrow a 4' level and see if your tank's stand is level. Then, check the floor underneath for level. Sometimes a stand seems level, but will flex with the tank + water weight it if the floor is not level and this can transfer that torque to the tank. Don't just look at the level's bubble, look along the level's edge to see if the surface dips or rises along the edge of your level. If you see a gap anywhere along the edge of the level, the surface is not even. I have an uneven floor upstairs and my house is not particularly old, just poorly constructed! I use adjustable feet (rated for a lot of weight!) on my steel 55g tank stand to compensate for my non-level floor.
If the substrate (the substrate under
) is not level, then another option is to use a sturdy piece of material for the tank to sit on that is level. You can actually ue small shims to get it exactly level, but make sure it's a thick, strong piece of material that resists warping over time. I'm going to use a 32"x18"x2" piece of laminated countertop material under a tank that I'm putting on a stand. The stand is actually too small, but once I mount this thick piece of material onto the stand, I'm hoping it will work. I have read of some folks using some thick (dense) foam/rubber material under tanks that helps fill any voids and level the tank, but I don't have any experience with that.
Again, don't worry about stand or floor issues until you can verify any problems. It could simply be a bad tank. It happens. If something was major out-of-level, you would have noticed it via the tank's waterline being off.
