I would go with a fluval if i was u. I dunno if u are new but i started with fish around 09 and have ac and i wish i woulda got a fluval but i didnt know anything about it and the petstore guy told be they are the best. They are for hob but not the best filter by far. Oh and i do have fluval 205 now and like it more than ac but both combos at the same time are great
