How often do you clean your canister filter?

Recommended Posts

Sprae

Hi all, as I've got my new Eheim 2213 running up to 4 weeks now for a 23L nano tank (as a 2nd filter), I'd like to know what other maintenance schedules are like.

I've heard that canisters should be cleaned every 4-6 weeks. But with such a small volume of water with two filters, I'm thinking maybe clean the filter every 2 months?

I don't clean mine until the flow is reduced greatly, even then with eheims I just backwash them usually. That being said I don't generally use any kind of fine sponge.. I guess my record would be no cleaning for 18 or so months, probably 3 months at the quickest interval.

I had scheduled every 4-5 weeks...stretched it to 8 weeks the last time, and a nano tank of mine had a huge nitrate surge (build up of crap), so best to do it every 4-6 weeks I reckon....just a quick rinse/squeeze with tank water...no major cleaning.

I don't use canisters.

But I guess all filters while different in the way they operate are for the same functions.

I pretty much clean mine when;

A) The flow is reduced.

or

B) The filters are not keeping the desired levels.

If I am getting good flow rate from them, And the nitrate levels are acceptable I leave them be.

My theory is, Why mess with something that's working.

I have a Classic 2217 on my 4ft and clean every 4-6 weeks as flow pretty much stops. I've managed to speed up the cleaning process by putting my media into media bags so only a handful of things to pull out and rinse. I also removed the fine and corse mats and started to use an internal Otto to increase the times between canister cleans.

I usually clean my canister filters every 4-6 months. Never really had an issue with that. Occassionally I clean it more frequently if I notice flow decreasing significantly.

Most my filters I clean only when the flow is reduced or levels are out.

I don't set a schedule because the large turn over or changes in stocking levels.

      Idk my tds but the rest sounds similar to my tap. If Grubs uses just dechlorinated tap water too then we probably would have the same parameters as we’re both in melb. And that’s my normal temp as well.  How do you keep them @Grubs?

      I would get a few if you like them, the odd loss of a baby shrimp wouldn't really be a problem. There are lots of shrimp people that have the dwarf Corys with their shrimps.As you say, it maybe better to wait a bit until you have more shrimps first but the cory doesn't hunt shrimps as food!

      I think that the shrimp in the photo is a female! Great you got the slots sorted so quickly and easily. The good thing with the amano is that they won't breed so you will never get more than you buy. Don't get too many though (may be the 5) as they are bigger and will out compete the cherry shrimps for food. Don't forget that there is postage cost with ProShrimp below £39 (I think that is the figure??) so bear that in mind as if you are close to that and you buy a few more shrimps you will get more shrimps for the same cost by not having to pay postage - f that makes sense? The other option is the tangerine tigers as they won't cross breed with cherry shrimp but you get a different colour - those are out of stock at the moment though!

      No nothing special. Just get them the right water parameters and that's it. @Grubs might have the perfect water parameter requirements for DAS, so see if he can list them. Otherwise, I used to keep DAS in water that was ph6.8 - 7.0, KH 4, GH6 and TDS of 200-230 and 25DegC.  These shrimp from QLD seem to handle slightly higher temps.

      Yeah tangerine tiger shrimp. I don’t think I would even mind that much if they procreated cuz I NEED MORE SHRIIIIIIMP!!!!  (And the offspring would be cute) Do they require much skill to take care of? (Either)
