Is this enough filteration?

  • We are currently upgrading MFK. thanks! -neo
I have a 55G with the following:

- External Cannister Tetratec EX1200 (1200litres per hour)(Mech)
- External Cannister Eheim 2222 (750litres per hour)(Bio)
- Internal Filter: Eheim Ecco (750 litres per hour)(Mech)
- Tetratec Airpump with 2 large airstones to keep the water circulating

I only do waterchanges of 50% once a week...

I have the following fish stock in there (approx sizes):
CK knifefish 9"
3X Oscars 8"
1X Fire-eel 10"
1X Royal Plec 5"
3X Pimelodius Pictus Cats 2"
1X Leopard Synodontis 6"

Also I feed them loads!!! hehe... but the CK is constantly hungry!
I would suggest you get as much as you can... as it is really nice to only have to do waterchanges of a couple of buckets once a week... nothing worse than having to do it after a long days work.

Also, I find that depending on the waterflow in the tank I can get a cleaner tank. I use the airstones and the spraybars to point all the debris to the intakes of the large cannister. If I get the waterflow wrong the tank gets a bit dirty quite quickly.

Aah and another thing, they are dead quiet!... only thing that makes a noise is the airstones but I keep those running to pump fresh air into the hood (I have this sealed tight as fire eels like to go on walkabouts at night) ;)
 
On my 75G I have a Rena XP3, and a Penguin 350 biowheel. My 45G has a Penguin 350 and a HOT magnum....never to much :)
