i recently bought a new tank and along with it came everything needed to run it... including an Rena XP3 I didn't test it before.

The problem with it is that if you put your hand in front of where the output is you can hardly feel any flow.

I think it could be from when I placed some eco-complete into the tank, but it was turned off in the process. The only thing could be that I turned it back on too early.

Either way, it was clean, and looked in mint shape when I got it.

I would just like to know some possible solutions, or what to replace.

I can be sure that it does not have a build up of anything to block outflow and it blows out the air inside the filter right away.

Thanks for any help!

What media are you using inside? The rated flow is with an empty filter, I believe. Once you add the sponges, floss, etc., that could drop your flow rate down a lot. Not sure what you have so hard to say if that's the problem.

You could test by taking all media out & then turning it on with just water flowing through empty XP3.

That could be true, buuuut the GPH is so slow... it is a spray bar also, so I will check.

I doubt it though because I have smaller filters (Fluval 304) with a spray bar that is full of media which has a creates a lot more current than this XP3 currently has, but thanks for your advice I will try that later.

May buy a new impeller because I will need some time or later probably ;)

I ditched the spray bar on my xp4 and the flow doubled. I will never use a spray bar again. I am trying to alter my eheims also.

Isn't the flow coming out not too big of a deal an actually better for plants?

I think if thats its just all the media in the fliter plus a spray bar. The only thing that matters is the amount of ammonia/ w/e getting to the biological bacteria so theres isn't much to do.
