I don't think I've seen that article before, Steve. I have read about bicarbonates and figured they'd pretty much help out where they can with no help from me. And I presumed the plants wouldn't have to work as hard to get CO2, if I just gave them CO2. But the article raised this point that I found interesting:
6. Keep the carbonate alkalinity up to at least 2.5 meq/l (7 dKH; 125 ppm calcium carbonate equivalents) to provide adequate bicarbonate for photosynthesis. Higher alkalinity may even be better, especially if the pH is also high, limiting carbon dioxide itself as a CO2 source for photosynthesizing organisms. This suggestion is likely already followed by most reef aquarists, but perhaps not by some with fish-only or related types of aquaria that also rely on macroalgae for nutrient export.
It sounds like my seagrasses might appreciate access to more bicarbonates.
