Killing the Canister Fitler Myth

[Fish]

Edit:
I should have made this more clear from the start. I am just suggesting that using a canister filter for mechanical filtration the way they are set up can lead to build ups of nitrates like we have been warned. I am suggesting throwing in LR and using it on our nanos as a biological filter instead.


Hello all,
If there is one thing that I can contribute to this hobby, it is putting an end to the phrase "canister filters are not for SW" or "they are nitrate factories".
Some nights I lie awake in bed thinking about all the nano tanks I've seen that would have been really nice if they didn't have a crummy little hang-on filter that has been stuffed with 3/4 of a lb of LR rubble, with a powerhead crammed beside it for extra flow.

The origin of the CF Myth
A canister filter will add nitrates to the water if:
1) You run it with all the crappy filter media and floss that's usually included.
AND
2) You don't clean the filter media properly.

But what if you filled the canister filter with LR rubble (and in my case, chaeto) like you do with your hang-on?
How is that any different? It is different - it's better:
1) the canister filter will hold many times more LR = better filtration capacity
2) will provide more flow, eliminating the need for extra powerheads
3) only the intake and outlets visible in the tank, making the display look much cleaner.

Please pass this on the next time you hear someone say 'canister filters aren't for saltwater'.

Without a canister filter, this tank would not have been possible:

Good luck out there,

Edit: haha I spelled "filter" wrong in the title - sorry
