Great Job... You can always cycle a tank using clear ammonia instead of using fish. Using clear ammonia saves you from the possible problems associated with the use of feed fish (parasites).
I would drain and level your stand bro. That's a hugh volume of water and with time you might start noticing stress fractures on that side of the tank. The seams way start to give way. Just think about if someone was leaning against you. At first you can support the weight but eventually you will give way. Your knees will start to buckle and your going to loose your balance than booya... your going to tilt over. Okay, maybe an over exagerrated point but better to be safe than sorry.
Fix it bro....just my 2 cents....![]()
