I am fairly new to the aquarium game. I wanted to start up a cichlid tank. i have a little problem with my filter though. The first problem is that the pump send water back into the tank from the sump with such power that i cannot have any substrate in the back corner because it all gets moved by the water. The other problem I had is that I used to have a bichir that I fed small feeders and i was findning that most of these feeders were getting sucked into the syphon and sent down into the bio balls. Also, since the intake is at the top of the water line, I have a lot of problems with fish food getting sucked into the sump as well. Lastly, I used to have gravel at the bottom and it gets way to dirty because there is no aggitation on the bottom of the tank. Is a wet/dry filter for me or should I invest in a canister?
