so i am looking at the maxspect gyre pumps and i like what i see, but i dont know if i can put this on my tank without a serious problem.- ie.blowing out the end of my tank. i have a 7ft by 2ft by 30in tank [265gal] it has a black plastic rim on top that is divided into 3 sections. i spoke to the manufacturer and they won't stand behind any tank without urobraceing. any opinions
