Thanks for all the advice guys
I will dig out a spirit level and figure out how bad it is (Though i already know its pretty bad)
Ill be getting a new stand for this as part of a CL trade on friday so i can see if that one will work better. If not, I will look into getting a piece of wood or something to level it out.
I cant cut the carpet away though, im renting and the landlords would flip if he saw that
I'll also drain it until then, i dont want to end up with a cracked tank and a mess
if possible, id rather not change location either, its kind of in a perfect spot and i arranged my furniture around it. though if it stays this bad, i will of course move it.
