Any case, beautiful tank! I also like the reds very much. Thanks for sharing. :-)
Well I would say that high output doesn't matter. The only thing that matters are PAR levels and assuming these started out close the substrate, only those at the substrate level. A lot more than light bulb/LED output goes into factoring that.
Low tech is driven by low light - meaning they achieved slower, sustained growth without CO2.
I agree that low light tanks can
have high tech, but they can sustain growth without it. High light (again, PAR levels here) tanks must
have high tech.
