I'm running a Marineland Aquatic Plant LED in 36 gal bowfront (21" tall) using substrate ferts, Flourish, potassium, and injecting CO2 (complete tank set-up is in my profile). My foreground & low-growing plants are yellowish-green and a red plant (Alternanthera) not so red. My other plants are fine, so I'm thinking not enough light. My light claims 172 PAR at 12". Not sure if that's accurate or if its strength has declined (6-7 yrs old). So I am considering a Fluval Plant 3.0 or Current Satellite Freshwater+ Pro, or other. Hoping to verify that either would be an upgrade over what I've got, and see if there are preferences out there between these two?
