Hey all,
I have been trying to set up a 180 gallon tank and I am running into two problems.

First. I noticed that the floor is uneven and that the left side of my tanks water table is 1/2" lower then that of the right side. the floor is a slightly slanted downward toward the left. What can I use to even it out and how?
Second I am using a mag18 on a Eshopps wetdry and overflow box rated for a 300 gallon system. My vendor told me the mag18 and overflow box that came with it are matched for each other. I am using 1 inch pvc that splits into two 3/4 inch return tubes. When I primed my overflow box I turned on the pump and was using the python to prime the overflow while I sucked out the air. Once the overflow started going I put on the pump and accidently left the python flowing, continuing to fill the tank. Needless to say, my tank overflowed and I was not sure if it was because the pump is too strong or if it was because of my stupidity in allowing the python to continue.
The only thing I can think of at this point is to put a valve at the return tubing to control the flow.
I have emptied the tank since and could really use some help on figuring this thing out. I am getting very discouraged and have even considered selling the tank which i rather not do. Anyone have any personal experience with the equipment I mentioned
Thanks for advice
Larry
PS: heres a link to the wetdry I own
