Recommend canister filter for 2ft tank

[jason6142004]

as above..

i notice that resun CY-20 and Eden 501 is quite popular.. i have a super space constrain which made me think of building my own canister filter but i fear for and failure and leaks.. and i am sleeping next to my tank, with the power socket very close, theres no room more error or leaks..

bio-load wise, not much of a concern as my internal filter is doing very well. but i wish to upgrade to a canister so that theres space for scaping

this is how bad my space constraint is:













thanks!!

CY-20 and Eden 501 are too small for a 2ft tank. They're more suited to 1ft or smaller nano setups. Perhaps you could try getting an Eheim 2213 for your setup since you are sleeping next to your tank. Eheim classics are known for reliability and silence

[vinz]

The recommended rate for a planted tank is the 3 x the tank's water volume per hour.

So if your tank contains 100l of water, look for a filter with a flow rate of at least 300l per hour. Slightly more (e.g. 3.5x to 4x) is ok, as the filter will clog and slow over time.

If it's too strong, you can always restrict flow at the filter outlet (never at the inlet)

but the classics' flow is super strong at 300l/hr for the smallest size.. how is it size wise?? i need one with the base area comparable with the eden..

which equates to about 150l/hr.. even the eden surpasses it.. my internal filter is doing 400l/hr and my bettas are like floating in the current..

[illumnae]

if i'm not wrong, the eden's 300li/hour rating is before taking media into account. so far reviews by other forummers find the eden enough for a 1ft, and too slow for a 1.5ft so hopefully that's some indication for you =)

as for the volume/hour, i find 3x is too slow for my planted setups. 5x seems to be a more accurate figure to go by

[jason6142004]

what is the dimensions of the base of classic 2211? how many red notes at polyart or c328?? What is the recommended retail price?

** Edit by Vinz: As if no local knows what a red note is? This is just a coded way to discuss prices, and AQ frowns upon the discussion of prices on the forum. Instead, ask for the RRP of the item. You can pretty much gauge how much the price will vary at the shops. **

Illumnae pointed out something I forgot... the effective flow rate. Even Eheim has changed what they list in their specs as each new model is released over time. On some models they list 2 flow rates. I cannot remember what terms they used, but one is for flow with media, one without. You want the flow with media to be at least 3x water volume per hour.

I think people have written in AQ that the Eden 501 slows down considerably fairly soon.

Another thing... flow rate varies depending on the media you put in. If you stuff in and compact lots of fine filter pads/wool, the flow will slow considerably. Never compact the fine filter pads/wool.

To play safe, get a higher rated one, and use a tapped valve at the filter outlet to control the actual flow in the tank.

The Eheim Classics do not come with a tapped valve at the outlet. I would suggest you get an Eheim Ecco, which have the taps. Also the priming handle will make priming the filter a much easier job, considering it's next to your bed and electrical.

(Yes, many have condemned the Ecco series for it's wonky priming handle, but I've never had a problem with the handles. There is a locking mechanism (I'm not talking about the manual latch on the cover) that prevents the arms from opening the canister when certain conditions are met (something to do with the valves being opened or closed). I suspect (without proof) that the handles were broken due to forcefulness. They are definitely NOT fragile)

[jason6142004]

what the RRP of the ecco??

Hi guys, I just bought a Eden 501 filter for my 2ft tank recently. My tank is around 58x28x28cm, which is around 50litres. Eden 501 is 300litres per hour which I think is sufficient for my tank. What do you guys suggest?

[oblivion]

as mentioned by some, the 300L/hr flowrate is before media is taken into account
after its filled with media, its may perhaps be slightly above 200L/hr thats my rough guess
i used one a couple years back on a 50x30x30 tank and i found the flow insufficient
and the tank setup then was like a bare rocks and HC iwagumi scape
so if yours is heavily planted the i reckon the flow will be even lesser
and imo it tends to clog a little too quickly if you try to load it onto too big a tank

do you run your filter through other equipments? UV, chiller, reactor etc?
i personally like more flow so for a 2 footer i suggest something with at least 600L/hr stated on the box
depending on your budget you should have a number of other choices
i would recommend a hydor prime 20 at 600L/hr
if you run a chiller then the prime 30 at 900L/hr will be my choice

[aquanatix]

I've been using a Hydor Prime 10 with the exact same flowrate with 0 problems for my 2footer as well...Guess mine is bigger then your Eden 501?Which means more filter media hence less need to maintain?

[oblivion]

i have a prime 10 as well
although its rated same as the eden501, it clogs much less easily

size may be one factor. i believe the way the flow goes through the internals of the filter plays a part as well

if i don't wash the eden every 2-3 months it may clog up
also have to open up the filter to clean the magnetic impeller

i encountered a couple of times after i off the filter for WC and tank maintenance, it won't restart when i on it back unless the impeller is cleaned

but i must comment that i LOVE both eden & the hydor for the autopriming capabilities
works a treat!

[Ah_ZhaN]

For a typical 2ft tank, I would recommend any canister filtration with flowrate from 450 - 600 L/hr.

Nice to hear another Hydor fan! Not sure about you but i just like the whole design and feel to it?Personally i kinda find ehiem alittle over rated at times?
Sure its been here since eons,spares are easily available etc...But sometimes the pricing can be a tad scary?Also,some of the recommended models are not auto priming ready?I'd like to think we've come a long way in terms of technological advancement,since you've been in the filter market since god knows when...couldn't you AT LEAST add in an auto priming feature?For the kind of price i'm paying,i'd at least expect myself not to be either blowing or sucking in tubings and face drinking aquarium water just to kick start the filter!(i myself have encountered this during the earlier stages of aquarium keeping!)No offense to Ehiem fans here,just some personal rantings from a Hydor lover! And yes...autopriming is definitely the way to go!

[jason6142004]

out of all these canister filters you guys mentioned, which one has the smallest physical size. i can only place the filter beside the tank. please look at the first thread to have an idea of my severe space constraint

[illumnae]

you could consider a hang on back filter (HOB). Atman has a HOB that is rated at 600li/hour, has adjustable flow rate and a surface skimmer as well. it would fit on the back or perhaps side of your tank, and the cavity for filter media is as big as an eden's so you aren't losing out on media capacity.

the downside is that being a HOB, it potentially can be noisy. however, if you keep your water level high enough near the outlet, it's quite silent. i have one in a similar set up to yours, also right next to my bed and the noise serves as a reminder to top up my water. once it's topped up, i can sleep easily.

oh, it's cheap too

[jason6142004]

but CO2 will be lost. not only that. my tank has the freaking black rim around the top...

[aquanatix]

Like illumnae mentioned,flowrate IS adjustable?If you tweak it properly your Co2 loss will be minimal if you're really that anal! Reasonable cavity for medium,literally "small"(hangs on tank?) and FOC skimmer! With various recommended flowrates,guess a HOB is something that would really suit your exact needs? And yes...HOB filters do fit on tanks with the black rim (AKA 5plan & Nisso brand types)as well so no worries regarding that!

[illumnae]

my tank is a 5plan with a black rim and the HOB sits on it fine. as for CO2 loss, if you're keeping the water level close to the outlet like i recommended for minimal sound, CO2 loss will be minimal as well

[jason6142004]

then what HOB do you guys recommend? but 1 thing. what will power my reactor?
