Trying to understand the theory and have a question that I can't seem to find the answer to. In regards to dosing, it is my understanding that we are dosing to maintain a sufficient level of nutrients such that there is no factor limiting plant growth. I'm confused in that, if there are sufficient nutrients, how come algae isn't growing. Yes the plants are growing, but we are dosing to keep levels up so why can't algae grow? And why does it seem that if we are out of balance does algae then start to grow, but not when all nutrients are available??
