So I was about to start cycling, the pump kick in but the pipes were leaking so I tightened them and plugged in the pump again and now it won't work. It says series 7 on there. This is 55g cube with 30gallon sump. Tank dimension 25Lx22Wx24H”. What kind of pump should I get? Another series 7? Any good brands at reasonable price. I have previoulsy used Mag 7 on my freshwatertank, they are good but expensive.
