FraserNZ Posted September 30, 2011 Report Share Posted September 30, 2011 I'm looking on Ebay at different Bubble Counter options available, however, I am not too sure which the best option to go for... I quite like the idea of having one that sits directly off the regulator. But I'm worried that water would leak from the Counter into the regulator as there dosen't seem to be some form of check valve? http://www.ebay.com/itm/Aquarium-CO2-CHECK-VALVE-Bubble-Counter-B-Regulator-/280746105813?pt=LH_DefaultDomain_0&hash=item415dc59bd5 Do any of you use these ones? Cheers, F Quote Link to comment Share on other sites More sharing options...

myfishybuisness Posted October 1, 2011 Report Share Posted October 1, 2011 yeap, i have had the same water in mine for 3months, none has evaporated, which means the water is not leaking anywhere Quote Link to comment Share on other sites More sharing options...
