The canister is about the same size as a 5G bucket I think it's the biggest ehime makes. Eventually I was going to add a gravity fed refugium, with the canister pumping from the tank to the refugium then back to the main. I'm just wondering what would be the best thing too put in the large canister Carbon and nothing?

Sorry Dabandit, I'm not planning on that much maintenance. I thought you you were thinking I had a smaller canister. I've seen O.C.D.'s tank and he has ran this type of set up for 8 years, His tank is crazy. He runs like 500lbs of life rock. But all he said in the canister was nitrate reducing media. I'm just wondering would live rock be better? or something else? I don't know his maintenance schedule. But really isn't the sump a place for equipment and the skimmer does all the work. So with enough live rock would the canister be better empty? Confused

Your only feasible choice for using the Eheim canister on a reef tank would be to fill it with live rock rubble and/or chemical filtration media of some sort like carbon or GFO.
Personally, I think having a big expensive Eheim canister to do these tasks is a big waste. With enough live rock in the tank, any in the filter would add very little filtration capacity. Further, a reef is all about flow and canister filters don't do a very good job of that compared to even inexpensive propellor driven powerheads like Hydor Korallias. Lastly, a $40 Phosban media reactor would get more out of chemical media than having sit in a bag in a canister filter. I'd sell the Eheim and invest that money some proper reef equipment.

Hi Trigger Happy I got your message. So let me straighten this out The filter works as the pump from the main to the fuge,then gravity fed back to the main with all little critters intact this helps provide food for the main tank.As for what I put in the canister that varies.Still looking for the best media, I did have de nitrate from seachem. you can run it empty.As for cleaning I crack the canister about every 2 or 3 months. If my nitrate starts to raise that is the first thing I clean. and I also clean my skimmer twice a week min. I also do 20% waterchange once a week. My carbon is ran through a reactor same with phosban reactor as well. I'm not saying this is the best method, just work for me.

Nothing wrong with running sumpless. Geez, everyone thinks there is only one way to do a reef tank. For sure, where possible, a sump is the way to go but its not the end all of reef tanks.
I would think some live rock for the tank would be a priority. However not a must for an fish only and depending on which fish. Some form of bio filtration would then be required. A media in the canister would serve that function, the same as fresh water, although that would not be my preferred way. Using live rock & sanbed as a bio filter is better than a media closed up in a canister. It could then be used for carbon and a phoshate removed and water flow. Be careful about gravity flow, without an overflow. Matching the return rate and downflow is almost impossible and a mess waiting to happen. If going with something like that, then perhaps drilling the tank is better.
