Hey all I'm new here! I have a 2KG FE setup in my Juwel 96, but I'm looking for a decent diffuser, but one that doesn't cost the earth..(cheapo ) I've seen a few on ebay, like these: http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... :IT&ih=011 http://cgi.ebay.co.uk/Co2-Diffuser-9000 ... dZViewItem Does anybody have any experience with these, and if so how efficient are they? Also, I've read about rigging it so that the CO2 enters the pump/filter in some way, how exactly does that work? Is it easy? Cheers, Paul.
