i need some ideas guys i have a 150 with peacock bass in it. it has a fx5 on it now. does a good job but i would like to add something else, my options are a AC110 or a fluval 405. or to make a smaller wet dry,sump setup i have semi limited space under the tank in the tank, so i cant put like a 55g sump or anything is it worth it to amke a small like 15g sump or better to just get the Ac or fluval
