Eheim Canister Filter Comparison

[Urban Aquaria]

So it does weaken the outflow of the Pro 3 600 right?I don't think my black phantom tetras and platies like the current strong outflow of my Pro 3 600.

Well, it should help to dissipate the flow... though if the overall current is still too much, just have to adjust the tap on the canister filter's outflow port to further reduce the flow rate.

You can also adjust the plastic lily pipe to point up towards the water surface to push the water upwards (you can see the diagram on the packaging), that will help to greatly reduce the current too.

Which is better at cleaning up the water in the tank?Purigen or Renew?

If I were to just choose between Purigen or Renew to be placed in my Ecco Pro 300 and Pro 3 600,which cleans water better?How many packs of Purigen or Renew should I put into my Eheims?I am confused because when I read up on Purigen and Renew on the Seachem website,both seemed to have the same functions.

Ecco Pro 300 is used for the goldfish tank while Pro 3 600 is used for the tank which houses platies,corys,sailfin mollies,black phantom tetras and livebearer fry.

[Urban Aquaria]

Yeah, both have similar features, but differ mainly in which specific effect they are more specialized in.

Purigen is designed to adsorb excess organic compounds, so it helps to reduce the ammonia buildup (suitable for higher bio-load tanks), but its less effective at clearing chemicals and medication.

Renew is designed as a milder version of activated carbon, and like carbon it will adsorb everything, so its more effective at adsorbing chemicals and medications (suitable to use after tank treatments).

I guess it depends on which feature your tank requires, though its also okay to use both at the same time. Just need to allocate sufficient space in the filter so that there is ample circulation of water moving through the packs.

sorry to interrupt..

I'm new to the planted tank world. I bought my 60x30x36cm (normal 2FT) tank but have not buy a canister yet. I've sort listed either to get Ecco Pro 300 or Pro3 350. Somehow, I like Pro3 350 more due to few reasons, but one thing I'm worried about Pro3 350 is that it could be way much overkill and make the tank like a washing machine instead. So, can anyone share if Pro3 350 is good for 2FT planted tank? If not, how about the smaller Pro3 250?
By the way, I plan to use the canister with in-line diffuser/reactor and also lily pipe.

I'm sorry if it mentioned somewhere in this thread, but having to read through 30+ pages is not easy, though I've about 10 pages but not much conclusion yet...

Its okay to use a slightly more powerful canister filter on a tank, if necessary you can easily reduce the overall flow rate by adjusting the inbuilt outflow tap on the Pro3 350 (it like controlling the water flow on a sink tap).

Using an inline diffuser or reactor will contribute to some flow reduction, and certain lily pipe designs will help to spread out the current too. In the future if you upgrade your tank size or add other equipment like a chiller system, there will be extra flow rate to work with, save the extra cost of having to upgrade the filter.

[DreamerX5521]

Thanks UA, you always here to give conclusive advice...

What I'm worried is the initial setup where the chiller is not added with the setup yet and how the canister flow control valve can be controlled, as I read somewhere mentioned that the Pro3 will still flow out water even the valve is adjusted to minimum setting. So, I can't gauge how the flowrate can be adjusted to the desired level. Anyway, I think I'll just going with the Pro3 350 as it can fill up additional 1.5L of media and hopefully it can reduce the frequency for maintenance. This is one of the reason I'm more lean towards Pro3 model.

Hi guys, recently gotten Eheim Classic 250. Before installing double tap, it was silent. After installing, keep on hearing humming sound from my unit. I've read around and found out that it may be due to air stuck inside and have tried shaking but to no avail. Any ideas of ways to keep it silent?

[Phillipians]

What I do it 2 things:
1) Tilt the canister and do a little shake. Not too hard though
2) When that fails, turn the canister on and off a few times - tends to be able to push out the bubbles

When both fails, I leave it alone for a day. It is surprising, but it tends to sort itself out after a while.

Hi all,

Planning for a new 2-2.5ft tank for gold fish. Any recommendation on the filter to use?

Hi all,

I am using Ecco Pro 300 for my 3 feet tank which houses 10 small Ryukins.Water outflow weakened by half in a month.Goldfishes still ok but think will get a lily pipe from original manufacturer to create aeration.

[RenesisTurbo]

Hi how often did u wash ur filter? am also thinking of pro 300 but not sure if it will be overkill.

I wash it once a month.Ecco Pro 300 is not an overkill considering my tank is slightly bigger than yours.

[Dscheng]

It is better to overkill than under power. Imagine i am using ehiem 2028 (1050 flowrate) for my 2ft tank. Hehe.

Does anyone have any insight on the pro4 model?

Is it out in Singapore yet?I thought it is only available in Europe or the US for now.....

Hi all,

I would strongly recommend sump type filtration system for goldfish. I tried canister before but not as good. Found filtration effect to be less idea and can't handle bio load plus need for more regular cleaning because goldfish eat and poo a lot.

Hi All,

I have a 4 yr old RES, kept it since it was tiny. Now that it has grown much bigger and stronger, it started chewing on my pipe that connects my pump to the overhead filter. I think it's brand is dophin? Bought it for about $40+. The pipe is made of plastic bah. This becomes a big problem as I have to constantly put it back so that water will flow through the filter. However, the pipe is starting to lose its shape and probably cant be used soon.

So I'm planning to get a new filter that will not allow my terrapin to chew and possibly remove the pipe, which possibly leads down to an external filter like eheim. As I was in the army when I had my RES, I had a little allowance to spend on my RES. Now that I'm in university, I'm a little low on cash. So I'm looking for something that is of the best value but still being able to handle my terrapin high bio-load. Hehe. Couldn't really find the prices of most of the filters online for the LFS, but roughly I know its about $200 for most brands, trying to find some that are cheaper(if there is).

My tank is about 39 gallons / 148 Litres. It's a 3 feet tank. Many thanks in advance for the advise!

Classic will be my favourite. Why spend so much on Eheim Pro unless you need the really pro features?

[RenesisTurbo]

Saw the new Professionel 4 600 at Seaview yesterday and selling at $440.Noticed that it looks the same as my Pro 3 600 except for a Xtender function.

Anyone brought and tried it out already?

[Frozenicex]

The pricing for the professional 3 and the pro 4 should be the same as per C328. Anyone getting pro3, might as well try the new pro 4 with nicer color accessories.

[TheKiwi]

Hey folks. Sorry if this question has been answered to death. Appreciate any inputs though.

I have a standard 2ft tank, running a Eheim aquaball 2208 and aquaclear 20. Looking to replace the aquaball since it takes up so much space and just has non-ideal filter media capacity.

I'm looking for a replacement canister filter. Not looking to cheap out, but also really just want something reliable and functional. I can do without fancy functions like self-priming. Anyone has recommendation?

At this point, I'm looking at a classic 250. C328 is selling them for $140 I believe, and might just grab that since I live just 10 mins away. That's around where I'm comfortable with spending. However if anyone has thoughts on what might be a better value for money, or just functionally more suitable, I would appreciate it. Thanks!
