Producing nitrates to feed macroalgae?
I have a question that I really need help understanding. It seems to me that having bio balls before a algae refugium would be very helpful. From what I understand plants will only absorbed nitrate when ammonia and nitrite are not present, as it prefers to absorb these first. Since there are many things in your system that can break down ammonia and nitrite wouldn’t it be best to have the plants absorbing as much nitrate as possible as it is the hardest to break down?
