Lighting/CO2 Relationship
I understand that optimal levels of CO2 should be 20-30ppm. I'm wondering if
in a low light tank like mine at 1.6WPG if less CO2 is optimal as less would be used by the plants? Thanks, Frank |

Lighting/CO2 Relationship
I think most folks will tell you "it's all about balance." You need to
balance nutrients with each other and with energy input and with the types of plants and fish load you plan to keep. That's why there's no pat answer and also why balance takes time to achieve: unlike mechanical systems that respond right away to input, living systems take time to respond and can also complicate matters by storing nutrients for a time. This makes determining the proper balance a time consuming matter that needs patience and note taking. To more directly answer your question: lower light means lower everything else including carbon, nitrogen, phosporus, potassium and trace element concentrations. OTOH, there's no problem I'm aware of with providing excess CO2 in the 20-30ppm range. jtm -- Remove NOSPAM for email replies "Frank Mamone" wrote in message . ..

Lighting/CO2 Relationship
You still need the correct levels of all the nutrients (inc CO2) in the water its just that you will be adding less to keep it at that level. So you still would be better with 20-30ppm of CO2 in the water whatever the amnount of light you have. It would be the same with any nutrient like potassium which yo would want to be approx 20-30ppm, the plants would just be using less of the nutrients and you would not have to add as much to keep it at that level. |

Lighting/CO2 Relationship
Thank you both for your great input.
The issue is that in my tank it seems that I need to sustain a bubble rate of at least 1 bubble per second to get that. I did find a recipe that gave me that output but it died after a few days. Could have been a leak. I don't mind changing the bottle every week. -Frank "Marcus Tait" wrote in message ...
