Ammonia poisoning is the single most deadly killer of fish grown in aquariums. Most of the times, Ammonia levels build up just after a new tank is set up. But, Ammonia levels can also go up when the tank "load" or the number of fish in a tank is just too high for the tank capacity.
Phosphates are a primary nutrient source for many forms of algae, particularly green hair species, so when high concentrations are allowed to accumulate in an aquarium, it opens the door for aggressive algae blooms to occur.
