tetra tec filters?

Has anyone used tetra tec 500 and 300 filters? I picked up 2 with a tank I just got and was wondering if I should use them or not.

yea u could. they use whisper cartridges, the bio-bag things. or if you could sell them on ebay as-is and make some cash to put towards a nice ac110 or emperor 400!

I was originally going to put 2 ac110 on this 130 gallon tank. But these came with it so I figured I would ask. They gave me a bunch of boxes of the filter bio-bags also.
