Refuguim

[gordypoo]

I have an Aquaclear 500 which i'd like to use as a refugium. I had a thicker piece of plexiglass cut to slide in against the motor housing. Although my flow is still too much. Is there a way to slow this flow? Any ideas would be appreciated.....thanks.

Howdy,

Take the black ring off the bottom in the intake tube in the impeller area. I have an AC500 on my 10G and this really helped to lower the flow to a managable level. I also put my plexi baffle on a couple inches right of the impeller housing as well and I think that helps. The last thing I did way put a little rio power head under the waterfall of the AC500 to help break up the flow and it seems to work very well.

Hoepfully this helps?

Can you switch the impellar for one from a smaller model? Such as a 150 or 200? I think that reduces the flow...

can't do it...the 110 has its own impeller that none other fits. i angled the baffle about 5 degrees and drilled 6 holes near the top...having done this i can use the pump at full flow and not have spill over. i tried removing the black collar and found no difference personally.

I haven't tried it but what if one cuts a few of the impeller blades off?

tried that too...definately works but if you cut off too much then the only thing you can do is replace it so be advised to cut slowly if you go this route.
