Hey guys. I'm looking into buying a canister filter. My tank is a Rio 180, it's reasonably well planted and when fully stocked it's going to house 2 schools of tetras and a group of cories.

I need some pointers. What brands should I be looking at, what capacity u think would get the job done and such. Also if u have a specific model to suggest would appreciate a few lines on maintenance, noise, potential problems with cleaning/priming...

Thanks guys.

I'm not familiar with your tank, but if that's 180 litres = about 50US gallons, I'd recommend an Eheim classic, 2215 or 2217. I'd go with the 2217. Mine are virtually silent. I clean them every 3 - 4 months. I like to use the spray bar. It really churns the surface. Never had a problem.

Agree with Plaamoo - Eheim 2217.

OK, seems we have a consensus.

Tell me, is the pump output variable in any way or is it just the one speed? How do u rate it in terms of connecting/disconnecting? I read some posts claiming its a messy affair.

Just one speed. The spray bar does spread the flow. You can buy one of the computerized versions that do have flow controls. Much more expensive and finicky in my limited experience.
They come with quick disconnectors that make it simple. Though I did break one of mine right off, not as strong as I'd like. It got stuck & I forced it. I would like it if they had media baskets as this is a minor inconvenience when cleaning but when you get used to it and develop a system it's not an issue. Especially since it's only done 3 or 4 times a yr.

Yeah, don't think I'll go for anything more expensive. The 2217 itself is plenty for my pocket. It was a front runner beforehand, just wanted to see if anyone here had a different opinion.

So how do u clean it if its just a container with different media in it? Do I take it all out or is there some fancy way of doing it? Also, whats a good combination of media anyway? What do u use?

It should come with all the necessary media. I first siphon off a good ammount of water from the tank to have enough to rinse all the loose media with. Top pad comes out mucky, I rinse this under the tap well and replace when needed. I dump the "coco puffs" in a strainer & then into a small bucket with tank water. This is the biomedia so take care not to leave it out of water too long. Then the course pad also gets rinsed under the tap. Then the little tubes get dumped into the strainer & then into another small container of tap water. I rinse the loose media well and replace the water until it's pretty clean. Remove the impeller & clean. then reverse the process as quickly as possible. I use a small powerhead & hose to refill my tanks so when the filter is all reassemled, I connect the hose to the outlet(top) and plug in the powerhead(in bucket of refill water). Open the inlet(bottom) with filter sitting next to the sink and outlet hose pointing in the sink until it shoots out, then close both quick connect valves and shut off powerhead/refill water. This will refill the cannister and make restarting easier. Hook the filter back upn & plug in. It will gurgle and sputter until it passes all the air in the line. Sometimes i have to shake it a bit to move the air, and once I had to unplug and suck on the outlet hose to get it primed, but not ususally.
It sounds like a lot but once you get a system worked out for yourself it's not bad and as i said, it's only 3-4 times a year!

Thanks for the info plaamoo.

With regards to the media I was wondering how u layered it?
Thought u might have found a better composition than the one from the instructions?
