Need help with Fluidized bed filter setup.

The question is whether you have specific problems with ammonia and nitrites or with dissolved solids (water looks dirty). If the problem is dissolved solids then a fluidised bed filter may not be your best option. In that case i would recommend a mechanical/biological filter that you could hang on the edge of the tank or see if you can improve the fine mechanical filtration of your current filter. Better still would be to upsize your canister filter. If the problem is ammonia/nitrites then the fluidised bed filter would be a good addition to your current filter. There are also brands available that you can hang on the side of your tank but you´ll need to install a powerhead (approx. 100 gal/hr) inside the tank to run it. One thing though, if you are having problems with ammonia/nitrites then the question is whether something else isn´t quite right with the tank. Points of interest would be whether you constantly have high ammonia/nitrite levels or whether they change constantly, and how much and how often you feed the fish. Once we know more about what exactly the problem is i´m sure you´ll get more than enough recommendations as to the best way to improve your filtration system
