Nyles Posted June 10, 2008 Share Posted June 10, 2008 I have done it to my ASM G-3 really simple make sure you have the right mesh, and get the smallest zip ty you can fing, I zip tyd to existing holes and trimmed up mesh so it did not interfere with cavity of pump, your good to go. Stand back and watch the froth take over! Quote Link to comment Share on other sites More sharing options...

mister crabs Posted June 10, 2008 Share Posted June 10, 2008 what do you guys use for the mesh? I want to do this to a Maxijet 900 for my cheapo skimmer i picked up at albany aquariums. I just need to find the mesh at a store somewhere as I have the fishing line to tie it on with. Quote Link to comment Share on other sites More sharing options...
impur Posted June 10, 2008 Share Posted June 10, 2008 Get the flat bottom mesh, its better for this mod. http://www.premiumaquatics.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=ENK-7210&Category_Code= Quote Link to comment Share on other sites More sharing options...
andy Posted June 11, 2008 Share Posted June 11, 2008 impur, how did drilling the airline directly into the volute work out? Quote Link to comment Share on other sites More sharing options...
impur Posted June 11, 2008 Share Posted June 11, 2008 I was messing with a GenX 4100 there, and drilling into the volute didn't work real well. The volute is just too small on the GenX pumps. I ended up making a mickeymouse venturi and it worked 100 times better than just putting the airline into the volute. Here it is The airmeter is tilted slightly, but it was pulling about 17lpm with the crappy venturi Quote Link to comment Share on other sites More sharing options...
andy Posted June 11, 2008 Share Posted June 11, 2008 Heh, I've found the same thing... the more I futz with venturis, the poorer my results get. The KISS principle seems to apply to venturi design. Quote Link to comment Share on other sites More sharing options...
WAVES Posted June 11, 2008 Share Posted June 11, 2008 they would work better if you had a way to Neck down the input. If the pipe is smaller just before the ventury when the water "expands" to fill the larger pipe, you will get the most air suction. Quote Link to comment Share on other sites More sharing options...
impur Posted June 11, 2008 Share Posted June 11, 2008 Yah i learned about that after the fact. I should have drilled that hole in the larger reducer fitting and it would have really ripped. I was just messing around anyway, getting about 30scfh from my octo pump at 41 watts Quote Link to comment Share on other sites More sharing options...
Frank Posted June 16, 2008 Author Share Posted June 16, 2008 OK got the mesh.... Now do I cut the needle' s off the wheel.. or just put the mesh over them Quote Link to comment Share on other sites More sharing options...
spectra Posted June 16, 2008 Share Posted June 16, 2008 How many set os wheels? If there is 2 you can cut one set off and zip tie the mesh to the other. Ask Impur as he told me what to do on mine. Quote Link to comment Share on other sites More sharing options...
impur Posted June 16, 2008 Share Posted June 16, 2008 I just put 3 layers on top and did not cut any needles off. Give it a shot and watch the wattage the pump draws. If it gets over the rated wattage, you might have to cut off a layer of needles to reduce the weight and bring the wattage down. But on my OTP3000 pump its only pulling 48watts with both needlewheels and 3 layers of mesh held on by small zipties. Quote Link to comment Share on other sites More sharing options...
