How do you determine secondary filters on a tank. I am running a FX5 on a 75 gal with a 10in rhom. It is plenty of filtration, but I was thinking of getting an aquaclear and stuffing it full of different pads for pure mechanical filtration. My fx5 only has the sponges and biomax, no pads (I had a post asking about these also). Instead of dealing with constantly opening the FX5 to clean pads I figured an aquaclear could be a better solution. Just curious if I can go with a small model (the 30) seeing its not the primary filter instead of doubling the cost and getting an AC110.
Thoughts?
