Shave impeller?

[DongShenYin]

I want to make a fuge out of an AC 300... how exactly do I "shave" down the impeller?

Hey!

Welcome to RDO!

I'm not quite sure what you mean by shave the impeller either. What's the point of doing it?

Hi there! Thanks.

Shaving down the impeller reduces the flow of water so that the AC can become a fuge.

Hmm, I don't understand the purpose. It should work just fine as a fuge without doing this. Just throw in a couple pieces of LR.

Welcome to RDO! (also check out manhattanreefs.org!)

what matt said sounds easier. The LR will slow the flow down a bit.

But if you still want, "shaving' the impeller down sounds like you take and cut some of the impeller blades. I'd go with diagonal cutters, and trim a little off each one. I'd trim the tops, rather than the ends. If you trim the ends, it would possibly cause the impeller to wobble and wear out the housing. Just my 2C.

if the lowest setting of the ac isn't slow enough (it probably goes down to <100 gph) then restrict the intake. e.g. add a foam sleeve

the mag pumps' foam prefilter slide over the ac300/500 tube. i use it more for anemone protection but if the foam cells are dense enough (sometimes they use denser material) it slows the flow.

Nevermind, I found a mini filter and switched impellers. Thanks anyway!
