Here's the issue. I want to start off without CO2, but have a light that can support CO2 in the future should I decide to go that route. So basically... I'm wanting to buy a light that can be used for when I do move up to having CO2, but will also be good for prior to having CO2.
This tank is not set up yet, no purchases made... So this is not an upgrade, it would be the initial purchase.
