What is the capacity of water and planktonic bacteria to oxidize ammonia or assimilate ammonia? Wouldn’t carbon dosing heterotrophic bacteria be a viable replacement for autotrophs and their requirement for surfaces? Seems to work in the shrimp industry. They calculate the amount of carbon they add based on nitrogen input. Given the light feeding of frags, the water might not become cloudy and the bacterial flocs could be food.
