Eheim 2213 Flow Question

[agutt]

Hi all,

I have a 20 gallon tall tank that has a 2213 running on it. Currently the intake is located in the back right corner, and the spraybar is in the back of the tank on the top aimed slightly upwards. My concern is that the spraybar is causing too much current in the tank. There are temporarily 13 Norman's Lampeyes in the tank until my 10 gallon finishes cycling. As soon as they leave, Rasbora Hengeli will be moving in. 5 oto catfish also occupy the tank. I am not sure if there is too much flow, all of the plants in the tank are 'dancing', the fish don't seem to be struggling but I could be wrong. To stay on the safe side i was considering modifying the way the spraybar works. My options are:

A. to point the spray bar at the back glass rather than toward the front of the tank.

B. To take a drill and put holes on the opposite side of the spraybar. I would do this by getting a drill bit and sticking it in the holes that are currently there, and then drilling through the other side.

C. drilling addition holes in the spraybar on the same side there are already holes.

D. buy some sort of different outflow pipe

Any input on this would be great. Thanks!

When I want to reduce the impact of spray bars, I drill more holes, make the existing holes bigger, or take the end bung out and add another spray bar on the end, or a combination of all of those things. I usually have the spray bar below the surface and angled so that the water "squirts" down the back glass.

That said, a 2213 is a big filter for a tank that size and no matter how you arrange the return, the turnover is going to be high.

is it that bad that the turnover is so high?

I also want to mention that I heard that classics don't live up to their rating. The 2213 I have heard is closer to 40 gal rather than 66...

anyone want to chime in on this?
