Ebay...2x9.99 takes a while to get them, but is worth the month.where did you purchase that??
Same guy I got it from.:biggrin:^ truth. i got one from some place in new york, $4.99 shipped.... and it is working great!
the ONLY reason a ceramic diffuser will not work with DIY CO2 is if you have a leak.do those work well with low pressure? my diy sits underneith my tank and my current ceramic fluval diffusor doesnt bubble at all...... so if i get one from ebay, will it suffice? and until then can i just use a cheap airstone at the bottom of the tank?
