It is a destructive modification though. When I ran an ASM (like a Euroreef only a bit more cheaply made - same pumps though), I did the mesh mod. It did make a significant improvement in performance (huge difference). Other than it didn't like to start after being turned off (I had to blow air into the airtube to get it going), I never looked back.

The Sedra pumps or rather their impellers however, are prone to swelling over time and eventually become unusable. So if it helps ease the mind process a little, odds are pretty good you'll have to replace that impeller sooner or later anyhow.

But .. IS your pump a Sedra? What pump is it now? (I'm just curious as it will help determine what other pumps we can look at, since you said noise is a consideration).

What about the pumps the Hydor uses? Can you get replacements of those? Because if so why not look at those (since you'll know what to expect from them..)

Whenever I look into pumps, the Eheim line of pumps comes up time and again as being one of the better ones in terms of quietness, reliability and performance.. at least people seem to think highly of them (I've never had one myself so can only parrot what I've read). Tend to be pricey though. Although AndyL (here in Cowtown) was selling I think a 1262 (bigger model) for a pretty good price a couple weeks ago (you'd be on your own for finding a needlewheel impeller though).

I do believe it is a Sedra, the sp3 or sp4 model number with EuroReef

My Hydor uses Hydor pumps, all three of them.

You have done the mod, would you want to help me with it, if I choose to try it?

Sure, although I did also do a thread about it:

.. in case you wanted to read about it first or something.

If memory serves though .. it may have made that "pump sound" a little louder. So you might want to see what other options are out there too.

Update on pump for skimmer:

Well, I took the EuroReef skimmer out of the refuge/sump yesterday to take off the pump and clean it. See if it quietens down some and to only find that I have fallen culprit to the common issue of swelling of the impeller magnet. It is actually cracked horizantally.

I went to Golds and bought a Sedra 5000. Others use this pump on EuroReef RS180's so I thought I would try it out. Cheaper than $300 plus shipping and customs from EuroReef in the US. The Sedra doesn't push as many GPH, but I can say that the air induction with the water is far superior to the GX-4100 pump that came with the skimmer.

Today, I am seeing things change as the pump breaks in and of course taking the skimmer out a couple times disrupts its stability. Where there was no real foam head happening yesterday, I am now seeing some good bubbling at the top with good brown foam production. So far so good. Not bad for $130 instead of over $300 plus plus plus

HMMMM... I saw where a guy modded his RS180 by drilling another hole and having 2 sedras hooked up. He stated it was even better. Something to think about.
