Cool idea ive got 10 510-T attys which i bought by mistake and plan on removing the tank spike thing. I was just wondering which size in mm 15mm 17mm 20mm 25mm. This ebay seller has a choice of sizes X 50 BASIL BUSH STEEL PIPE GAUZE SCREENS CHOOSE DIAMETER 15mm 17mm 20mm 25mm | eBay.
The originals in the black sleeve that I used were 20mm and really just a little small for a complete circle in the atty. So either the 20 or the 25mm should be good.
