patchy Posted November 12, 2005 Share Posted November 12, 2005 what ppm does "optimal" or 'green' mean? doesnt say anywhere.... Link to comment Share on other sites More sharing options...
Ged Posted November 13, 2005 Share Posted November 13, 2005 I presume you mean the Azoo CO2 Indicator AZOO CO2 INDICATOR For aquatic plant aquariums The AZOO CO2 INDICATOR can constantly monitor the CO2 level in water plant aquariums. The CO2 level should be tested continually to ensure an optimum living environment for water plants. Yellow-Green: Excessive level of CO2 Green: Optimun level of CO2 Blue: Deficient level of CO2 I couldn't locate anywhere the ppm as it just measures the presence of CO2 and not the exact amount. I hope this helps Ged Link to comment Share on other sites More sharing options...
patchy Posted November 13, 2005 Author Share Posted November 13, 2005 thanks for the help Ged but i've already read that. It's the same thing on the box... Well i guess optimum is between 20-30 as thats what i gather from aquatic plant people. by the way right now it's 'green' and it's in a light-med stocked 100 gal tank with 1.3wpg and med planted, no additional Co2 and light aeration. Does this sound right? Link to comment Share on other sites More sharing options...
