Title: Meshwheel Mod
Post by: bigfalcon36 on March 07, 2007, 18:22:37

I did the Meshwheel Mod to my ASM G3 last night.  I has made the performance of the skimmer go through the roof.  I have a really low bioload as it is, but my skimmer is still pullling out some pretty sick skimmate.  I give the mod a thumbs up...I think everyone with a middle of the road needlewheel skimmer should do it if they want to improve their skimmer's performance.

Care you tell us how to do the meshwheel mod?

Yeah, it's not too difficult.  I got the mesh material from a guy on RC that sells it, just PM A sea K and he'll take care of you.

Here's a good tutorial:

This guy documented it well and took some really nice photos of the work. 

Here's the original thread from RC that got this whole thing started:

you could glue almost anything in there as long as it has clearence.  its just breaking the bubbles into smaller ones.  more bubbles the better

Also, if you can enlarge the hole for the venturi hose to draw more air you can increase the performance.

is there a limit on how large the hole can be?  i know on cheapo skillers to much air drowns them out and screws with the skimmate.  with a large pump is there a limit to how much air you can draw in?  or could you in theory hook up a garden hose sized tube?

i guess you could...but you'd need a way to penetrate the air into the water.

The larger the hole the larger the pump has to be.
Remember, the only thing that makes a venturi work in the 1st place is restriction.
To much air will slow the pump down to much due to to little restriction and introduce to large of a bubble to be efficient.
That's why a true venturi valve looks like two inverted cones on the inside.
They restrict the flow so the air can be injected rapidly in a jet stream effect.

Think of it like a fuel system on your car.
To much air she no goes. To much fuel she no goes.
Equal mixture ( maybe a little lean) and it purrs like a kitten.
