newbie, CO2, observations, and algae
At the risk of .....mis-using this forum, I want to share with you an observation.
As a newbie to aquariums, and as someone discovering the mysteries of setting one up in somewhat of a vacuum, I discovered
1.5 bubbles/sec of CO2 with a kh of 4 gives me a ph of about 6.6 and CO2 of about 30ppm
3 bubbles/sec of CO2 with a kh of 4 gives me a ph of about 6.4 and CO2 of about 48 ppm
It's easy to see where a newbie might not want to DOUBLE the injected bubble/sec rate for fear of sending CO2 through the roof. Of course this is exactly what may be needed to reduce algae.
It is almost impossible to get the subtle nuance from reading these forums that really can only come with experience.
