those types of filters are not good in marine tanks... now if memory serves you are not looking to do a sump..correct?
if not here is a really simple DIY to help you out and save money!! grab an aqua creal filter the largest you can fit on your tank... google Aqua clear filter mods or HOB refugium
this will show you how to make it into a fuge.. you can run carbon chemi-pure (highly recommended for the small tank) and even cheato (macro algae) in there.. this would be better for your system than a canister..

the cost for an aqua clear is about the same as the "Eheim Classic External Filter - 2213"
what's better about the aqua clear then the extremal filter?

Angry What media to use in external canister filter

Hi, when I set up my 60gl tank for FOWLR I was sold an eheim external canister filter with bio media. Having been running for about a year my Nitrates are high and not able to keep them down. Having read the posts on here about the filter not being any good for marine use, can anyone suggest what media to use in the filter so it isn't a nitrate factory.
I really don't want to do away with it totally as I spent a lot of money in the first place.

I have recently change what I have in my canister filter and what I do when I change water.

in my top basket I have medium size crushed coral.
2nd basket I have a sock of a phosphate remove.
3rd activated carbon in 2 socks and splinter basket.
the other side of the canister filter sponge which when I do my 5% to 10% water change I remove the sponge and wash it under hot fresh water witch would kill the bacteria that would cores nitrates to be produce.
