Is Eheim 2026 enough for a 422 tank?

[Aquaculture]

Hi guys, I'm wondering if an Eheim 2026 filter enough for a 4ft x 2ft x 2ft tank.

If it isn't, is it possible to attach a power head at the water outlet of the filter to give it more flow rate?

Thanks.

it probably isn't enough. i'm using a 2028 for my 4x2x2 and i'm starting to feel it may not be enough

Would it help if I attach a powerhead at the output of the filter to give it more boost?

I'm not too sure of their cost but I think a powerhead is cheaper than a filter.... but am not too sure if that setup would work a not.

If not wrong, attached powerhead to output is not advicable. For mine 4x2x2 tank, I have 2 x 2028. It really depend on what kind of flow you are looking for.

Oh! Thought of saving money and space.

I'm hoping to have sufficient flow rate to prevent BBA, spread CO2 more efficiently.

I'm curious about the 2 filters set up. Do you set them up as stand-alone units? Or the filters are connected like inlet -> filter -> filter -> outlet?

I have it setup as stand alone. If really 1 break down, I still have the other filter working. Also it is easy to wash up, will not disturb the water flow ..

Think I've to shop for a second hand one...

Btw, both yr filters provide CO2?
