Canister filer (Eheim 2213) for CRS

[CRSenthusiast]

Hi fellow shrimp keepers,

I am running a Eheim 2213 filter on my 3 foot CRS tank. I normally switch off the filter at night.

Am I supposed to switch the filter off at all or not?

Also how often does the media need to be cleaned or replaces on these filters?

Thanks,

Don't turn the filter off, you'll starve the bacteria of oxeygen causing them to die off and create ammonia spike, you should leave it on all the time or not have it in at all. I run mine empty so I don't know sorry.

wow.. definantely leave it on at night..

you wont need to change filter media for a long while..

I personally run a 2213 on a 1.5 foot, 70l tank with a sponge prefilter as intake and 2 other sponge filters running all the time.. i just need to clean prefilter every 3-4 weeks when or flow slows down.. cannister insides after 6 months or so..

i never turn my filters off.. and i provide extra filtration as ive found it to be best..

hope that answers a few questions..

Never turn off your filter and I don't think a 2213 on a 3ft will be enough if that's the only filtration you have

Thanks guys,

I also run a sponge filter through a air pump.

No wonder I was losing them every now and then.

Will not switch it off now ever. Thanks guys.

also anyone know where can i get a prefilter for Eheim 2213? currently i am using a net around it.

Thanks,

Get a pre-filter sponge like one Fluval sell for their HOB intakes. Like these http://www.ebay.com.au/itm/251046077021?var=550126091206&ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649#ht_1717wt_906
