Are Canister Filters a MUST for a Planted Tank?
Let's discuss. :-?
Yep, less equipment in your tank
However, HOB filters are an option for nano tanks
IMO, I think it is wholey budget dependent. The flow rate and water volume turnover is the most important factor.
I have to say no on this one. I have a Juwel tank with the internal still in, it's in because when i got the tank my little one was at the crawling stage and i couldn't afford 50g of water on the floor, if he'd played around with the external filter. I have ran this tank for a year now and had no problems. I am going to change it to an external soon though.
I think its a bit of an ambiguous question really.
Is it a must in terms of necessity? No. The scapes that use internals or other filters prove that wrong.
Is it a must in terms of benefit. Well not a must but definately more beneficial than internals in terms of aesthetics, media capacity etc.
However the latest research Tom Barr has done comes out in favour of wet/dry filters over cannisters in terms of CO2 and O2.
I don't even think it is needed for planted tank, especially if you do not have fauna inside. The plant do need flow but that can be accomplished using powerhead or wavemaker.
Dead material/leaf can easily be siphon during weekly water change. Ammonia, Nitrite and Nitrate will be use by plant during photosynthesis. Whatever left over will be reseted during weekly water change. So I wonder if filter is really needed
Shadow makes an interesting point here... has anyone ever made a tank without a filter? Just using powerheads?
I am quite relieved after I started using my home-made canister for three things...
1) It holds quite a lot of media and needs very little maintenance.
2) obviously saves good space inside a tank
3) I can put more bioload to the tank(yes, strangely I like a big bunch of fishes in my tank), because it can handle it without choking at all.
This is w.r.t an internal filter.
@AC...sounds interesting, can you link us to the Tom's wet/dry research post.
@Robert...we atleast need a filter initially after setting up the tank first(even for a fishless tank) to clear up all the floating particles or cloudy water.
I've been running external pumps into spray bars and using power heads with aqua clear powerhead attachments as mechanical filters for the last 10 years. co2 24/7 always have some algea various types, do 50% water changes weekly without fail. Turnover is varies from tank to tank 5 to 10 times per hr. I am at a point where i either go with a bio filter or shut down my co2 at night. Sick of seeing all these algea free scapes although mine don't show that much algea i know it is there. % tanks totaling 460 gals. Maybe a central filter using overflows keeping the mechanical filters.
Ermm.....Someone quite 'famous' called Diana Walstad. Originally just the plants filtering however these days she follows the same rules as other planted setups (from what I am led to believe in regards to needing some circulation/flow within the tank.
I believe (and don't quote me) that she now uses powerheads for circulation whilst still using the plants/substrate/other bacteria colonising as 'filtration'.
Wouldn't interest me going that far as water clarity is of the utmost importance to me to the point that I would not be without purigen in my filters. I want gin clear. The filter isn't really there fo other means, just to keep my water 'invisible'.

The short answer is of course no, since it's been proven you don't need one to have a successful tank.
With that being said I think the canister remains the most practical way to keep equipment out of the tank which for me, if we are talking aquascaping is an absolute must. I personally don't want any equipment especially powerheads all over the place only to be removed for a perfect shot. I want to enjoy the setup all the time, which would require minimal visible equipment.
On a functional side, I think the traditional filter is much more important during startup. It allows a place to put organic removal media, etc to aid in biofiltration until the 'real' biofilter gets up to speed. Once this happens, in most setups the bulk of the filtration is taking place in the tank and the filter becomes more or less a flow device with mechanical filtration.
I do the same myself!
the simple answer is no. they dont need canister filters.
I´ve been doing this on a nano, powerhead only, 50%wc every other day and I was ok with EI dosing, plenty Co2 and light. But as I switched to weekly wc Glosso turned mad and I became algae issues.
I'd say it depends, mainly around what fish call the tank home and the number of them..
I didn't know much about canister filters until I got into the planted aquarium hobby. Back then, I was using HOB filters for quite sometime until I came across canister filters. I think in the long run, canister filters are more economical and suitable for larger tanks.
And thank god for DIY quilt batting filter media, and external heaters, plus external CO2 diffusers...all hooked into the cannister hoses...that is another good reason for cannisters.
We all know: your filter is the basic need for an good functioning aquarium. The bigger the use of filter mass, the bigger the stability.... Not everybody do have a lot of room for place an 1:1 open biologic filter system and has to works with a more handy system like a canister or hang on filter system or what so ever...... :yo:
As a former heavy HOB user I think canisters are a must.
Maybe yes or may be no, depend on budget and how big is ur tank, if it's nano, HOB is easier,if u got more money,u can rethink of canister
