magvi, I got your PMI am getting some mesh from fellow reefer, he's got some leftovers. I am sure this had been asked and answered bazillion times. I have Sedra 5000 non recirc on ASM G3. Could you repost or point to the meshwheel instructions for this pump please.
Also, if anyone knows does leaving some or all pins on the original impeller makes sense?
i cut all the pins on the wheel impeller .
1. cut the pins (be careful on the finger) .
2. make more holes (you want to tie 4 zip ties you can see in the picture)
3. cut the mesh (3 layers)
4. add all the mesh together on the wheel impeller and put the zip ties you start to insert the zip ties to the close hole to the cneter of the wheel like that when you tight them the big part of the zip ties will be far from the center of the wheel impeller and will not touch the washer .
5. start to tight the zip ties again by circle
6. trim with scissor the mesh to the diameter of the wheel impeller (do it form the back like that you will not damage the wheel)
7. cut with small cutter the center of the meh where it's the washer sit but don't cut a lot small piece and move the mesh from the center (if you make big hole you lose more air and youwant to get maxair fromthe wheel)
8. put back the wheel impeller in the pump and turn it manual wit the finger verify the mesh not touch strong the pump body and the shaft free also check the washer sit good on the center of the wheel .
9.close the cover of the pump and turn it out the body of the skimmer first test (put the elbow on like that the water will not splash)
if you see the pump spin it's good sign and youconnect it to the skimmer body .
some time ppl have problem to spin the impeller the reason it's because : the mesh to strong at the first time and after 3-5 days it's will start regular without problem . also the magnet on the impeller can be weak and the first start hard. or the mesh touch the pump top or body and can't spin.
now when it's run take out the air control valve and leave the air pipe free .
reduce the water level a lot not like you do with the regular wheel impeller (just for the first when you find the correct position after it's break in you will know where it's need to be)
give the skimmer 2-3 hour to break in and after youwill see the bubble get more smaller you can know it's break in and start to match the water level to skim wet/dry
if you want to put after all the air valve you will get more tiny bubble but keep it full open because you increase the pump watt with this mod and if youwill close it (clock 1-2 ) the watt will increase 50% more and youdon't want it .
on the first picture you can see the mesh top and how the zip ties sit on it :
on this picture you can see from the side the zip ties insert the mesh (not cross) and how it's look little puffy.
last part :
when you finish the mod and get good result please post some picture , if you need more any help i will try to do my best .
if i forgot to mention something please forgive me.
good luck :lol:

question: what control air valve are you talking about? In my skimmer there are no such thing, I think. The air tube connects directly to venturi fitting on the pump, without any valves.
