Nitrification, denitrification and algae

[Randy Holmes-Farley]

So im thinking what if i introduced other means of competition like good bacteria and housing for it? If i had it to begin with would a potential ammonia spike be consumed faster and all this algae and pests would never take place?

It's possible, but I do not know if it would be especially useful in practice as the nitrifying capacity will level out to meet the available ammonia. If you provide more space for it, it may just spread out over that larger space with the same capacity.

Growing macroalgae provides this same benefit, and may be less prone to getting disturbed.
