maxijet output

I am giving my new AP 24 a leak test right now, and I am a little disappointed in the output I am getting from my second Maxijet 900. I have the pump Y-ed off using loc-line. I expected to get some significant current coming out of this, but when I put my hand infront of the nozzle, I can barely feel a trickle. I am assuming there must be an issue, don't you think? What kind of flow should I expect?

As an FYI, I also replaced the stock pump with a MJ 900 and Hydor and it seems to be doing much better than the other.

I get the same impression from my maxijet 900 in my 24g Aquapod it just doesn't seem to have much output (of course neither did the stock pump). I'm not sure if it has to do w/ how far it has to pump the water up first or not. I intend to shorten that tubing raising the pump itself and seeing if that does anything (I doubt it). Just haven't had a chance yet.
 
I replaced my stock pump w/ an mj 1200 and was still disappointed wit the amt of flow, so I upgaded to the rio 1100 which puts out 350 gph at 1 foot head height. Finally I'm happy with the amt of flow in the tank.
 
What about movement in the sump area? The water in there is still in mine. Do you see movement in your sump?
 
I still do not really see movement on the pum side of the sump, but it's definitely moving in there, it's just pulling from the bottom. If you raise your return pump you will probably increase the surface water movement in that chamber.
 
Try shortening the hose from the pump to the bulkhead. Even a few inches shorter made a large improvement in flow. Also, make sure there are no kinks and that the tubing fits well into the bulkhead (there was a little water movement back into the fuge area, once I fixed that there was a big increase in flow)!
 
From everything I've read, the MJ1200 is a better fit for the larger nanos while the MJ900 is better suited to the smaller ones. I run a 900 in my AP12 and it's just barely enough, even after I drilled the manifold.
