Eheim ProII 2026

[MdmBudak]

Hello,

I'm currently using an Eheim ProII 2026 for my 3ft(3ft by 1.5ft by 2ft) setup.

I'm considering upgrading to a 4ft tank soon, will my 2026 be able to support a 4ft fully planted tank?

Thanks

Shouldn't be a problem.

I do have a similar setup. I even have to lower down the output current.

if you must upgrade, I believe the appropriate one should be 2028 for 4 ft. I just setup my 3 ft with ProII 2026 too. The shopkeeper recommended 2028 for 4 ft.

however I am not good at calculations. I measured the water volume to 162.36L or 42.9 Gallon whilst the recommended for 2026 was 350L or 92 Gallon. Did I make the right move? comments?

How big a 4ft tank are we talking about 4x1.5x2 or 4x2x2?

For the former, a 2026 just is just about enough to have proper circulation for the whole tank and it pretty much determined by the layout and type of plants you are considering.

For the latter, a 2026 is IMO not sufficient...you could, but I think you may be prone to having poor circulation induced algae.

Sorry to hijack this thread. I have a 2026 for a 4 x 1.5 x 2. I noticed the output current damn strong. Can see water movement all the way from the left side of the output to the 2/3 third of the tank length. Should I lower it? Or is it better to push it to full blast?

Did you guys use the rainbar? I do have a 2026 for a 3ft but I do not use the rainbar. Only a part of the tank water has a strong flow and that's around the output area.

The rainbar will have a larger surface of moving water. Disconnect the rainbar and use a pipe elbow as the outlet. Also the placement of the output tube is also a factor.

[N.I.N.]

No, I din use the rain bar. Water comes out from the CO2 reactor, with the outlet close to the bottom. Dunno why the current so strong also. I could see the speed and movement of the tiny co2 bubbles and some particles. The outlet is facing the side glass.

[BFG]

Are the outlet and inlet at both end of the tank?

[N.I.N.]

outlet on extreme left side and inlet on extreme right side.

[BFG]

On my 3ft setup, I had put together the outlet and inlet on 1 side of the tank. However, the outlet tube is pointing to the other side of the tank so that the water has a longer area to flow.

According to this site, the pump for 2028 has a higher flow rate but IMO, does not differ too much. The main difference I see is that 2026 only has 2 media basket comparing to 2028's 3 media basket. I think the main concern is whether 2026 (2 media basket) is enough to generate enough bio filtration which is rather critical in our planted tanks.

[PeterGwee]

I beg to differ on the importance of bio-filtration over mechanical filtration in a planted tank. Plants are natural bio-filters and they are always the best. In terms of bacteria, there is already loads of them inside a planted tank both on the leaves as well as the substrate. Additional bio-filtration only serves as a backup in case things go bad such as poor plant growth. Good mechanical filtration helps to polish the water and always keep it clean and dandy which plants are not able to do it.

i agree with peter.......check out this site on alternative cycling methods of a new tank: http://www.csd.net/~cgadd/aqua/art_plant_newtank.htm
