I am not a particularly active member on this forum mainly because I am English & post on the English forums but I do find it interesting how you guys pay so much attention to light as there is a very different perspective from where I come from ...
We believe you don't need to use high light because you are enriching your tank with CO2 and in fact, as we try to point out repeatedly, enriching with CO2 actually allows you to use LESS light, the more C02 the less light required & therefor less algae That's how amazing CO2 is!
Here is a nice long read ....
