guy at lfs suggests a fluval fx5 for my 56g freshwater tank but then im gonna use it on a 90g saltwater tank later on, he said they are having a sale with them for 230 marked down from 350, good deal or not? nic said to get a refugium for 90g saltwater tank, but guy said that that filter will work for it as well?
 
You really don't need an fx5 for that small of a tank. You could just go with a fluval 405.... I think that is what it is called. The Fx5 is a good filtration choice for larger tanks, but you can get better results from making some of your types of filters. Do some research and possibly save lots of $$$$.

my research so far has yielded that a fluval 405 (purchased locally) is 200 dollars. he said that i can turn it down so my tank isnt a whirlpool, but a 405 wouldnt be quite as sufficient for the saltwater tank.
 
I wouldn't put such a heavy duty filter on a 56 gallon tank.

Also, canister filters are not the best choice for saltwater. Nic is right about the refugium. A macro algae and live rock/live sand filled 'fuge paired with a good skimmer will keep nitrates down in a saltwater tank better than anything else. With a canister filter you would have to rely on a constant supply of fresh chemical media ($$$) to do the same thing.

i was going to do live rock and live sand in that tank along with a filter or refugium?
 
I hear "natural" filtration is best for salt water.

Also, I have a Fx5 on my 55 gallon tank. It works FANTASTIC! When using the standard output nozzle I had it full blast since well, it didn't create much current, but after I switched to a 90* nozzle I had to turn the filter down to about 75%.

The slower the flow through the filter, the better the filtration as long as your getting the right turn over rate.

but im still going to do live rock and live sand. having more types of filtration really helps though.

btw love the avatar lol
