Now i have just set up my Fe co2 setup and all is well but im struggling with the diffuser as it does not seem to do anything which is odd. My tank is 320l and
i have one of the following: http://cgi.ebay.co.uk/Aquarium-Co2-...m&pt=UK_Pet_Supplies_Fish&hash=item2a02961cd1

from e-bay attached to my eheim 2128 on the outlet pipe. http://www.charterhouse-aquatics.co...onal-freshwater-thermo-with-media-p-1128.html

now the problem is i get no indication of co2 bubbles at all in the water unless i turn the co2 all the way up to a silly amount like 10-20bps if i put it down to normall 2-3bps i dont get any indication of co2. I have checked for leaks ect and no issues.
Also my drop checker with 4khd soloution and blue stuff (bromtho blue or whatever from my test kit) shows dark green when off or on

should as a co2 beginner try another co2 diffuser so i can defo make sure that the co2 is getting into the tank?
Any recomandations on what type of co2 diffuser to use?

cheers

Maybe the bubble was 100% dissolve. What is your tank size? maybe 2-3bps is too little thus drop checker only indicate dark green. you can see bubble coming out when you set to 10-20bps telling me that your connection is OK.
