Doesnt anyone remember grade 9 science class? Plants need darkness to photosynthesis properly, studies have proven this. You want the most out of your macro algea it needs atleast 10hrs of darkness with a 12 on /12 off pattern showing the most photosynthesis in plants.

I am glad your showing good growth but growth doesnt mean photosynthesis which is what takes out nutrients.

well with a continued increase in mass that I keep throwing the stuff out, I'll assume it's removing something from the water column.

Pardon my disagreement...
Photosynthesis is the process plants (and some animals) use to fix carbon used to build the structure of their bodies. During photosynthesis carbon dioxide is consumed, the carbon from the CO2 is fixed to form organic molecules for building the organisms structure, and providing sugars used as metabolites for energy, and oxygen is exhaled.

If photosythesis is not occuring, then there is no carbon fixation, and consequently no growth. Consequently, growth DOES mean photosynthesis is occuring.
