using canister as biological filter??

JUNRL · 12-19-2001, 12:27 PM

i have an old Eheim 2213 canister filter and was wondering if i could use this as a biological filter for my 75 gal tank. i've read that as a mechanical filter, this could cause more of a problem in reef, in that waste accumulated turns toxic.
what if i don't use foam filter in it but only ceramic tubes or bio-balls.
i'm new in reef, just starting from FOWLR so i don't have a sump yet.
thanks for the advise

I used an Eheim for biological filtration initially, thinking that as long as I paid so much money for it, I would use it dammit!

I continually had low levels of nitrates, which were eliminated when I converted to a DSB. You don't need the canister at all. I use a Magnum canister now to run carbon only.

does this mean a canister has no place in reef?
what a waste of a good looking equipment. i couldn't use this on my small fresh water tank, it's too strong.
thanks anyway

Yes, that's pretty much what it means. You want to confine the biological filtration to the live rock and the sand bed.

I bought an eheim 2227 and I have an aqua medic protein skimmer. I have a small 15 gallon tank. Should I convert the tank into a sump??

Hi energyguy, Welcome to Reefland!

I would not use the Eheim, if possible take it back and get a refund. The use of these types of mechanical filters is not required and can lead to problems if they are not actively maintenanced.

If you do not have a sump, then yes I would try to incorporate a sump on any marine system for the added water volume and a place for equipment. This provides you with a nice place for your protein skimmer, heaters, any probes that may be used and provides extra circulation with the return pump.

What kind of tank do you have?

I have a 55 gallon oceanic. what kind of pumps do I need to convert it? Is there a good do it yourself page for sumps?

This forum has tons of information on setting up a sump and what is required to do so. I'll post some threads here that you can sift through and if you have any specific questions, feel free to post a new thread.
