Canister Filter, Good Or Bad

[svirid]

Good day,

I have recently purchased Eheim canister filter and now I have 2 standard filters in there one Blue and one White color. Now I have read some information and many people are saying that its a collector of Nitrates? Is that true? What can I do about that? Can I remove those 2 filters and replace them with biological? if yes, which one would you recommend.

Thank you for your help.

Live rock, high flow.

One thing you can do is prefilter the filter so large particals are not going in there, then put LR rubble in there. You will create a refuge for sponge and fan worms. Dont pack it too tight. What you dont want is the media that has no anarobic zones, like ceramic doughnuts or bioballs.

Sorry for bothering you but I was trying to find where I can buy LR rubble online and could not really find it. Is there any other name for this or maybe you can give me a link to how it looks like in a real live, package or brand. I am just afraid to buy something that will kill my tank.

Thank you for your help.

many lfs will sell off the rubble from their live rock shipments for a song and a dance
certianly you could just talke live rock and bust it up. There must be a reef club in Toronto. Just ask/post for some rubble from an established system for your cryptic canister fuge

Its not really a branded thing, its just scraps of rock.

IMO nothing beats some good old fashion mechanical filtration, for me, it made the water clearer, it removed quite a lot of waste, and was an easy way to remove detritus from the tank, sure beats basting and sucking water out of live rock.....

Comes with a price, clean every 1-3 days to prevent nitrate factories. Since you dont really need much bacteria in the filter itself, ive always just cleaned mine under tap water directly, all my bacteria is in my live rock.

Doing this probably does the exact opposite of cause nitrates, it helps prevent since it is removing wastes from the tank.

Bio-balls and ceramic media.... na, no need for that.
