For phosphates you can use molybdate solution but be careful it contains sulfuric acid.
plant nutrient
The predominant ones are nitrates, carbonates, sulfates, silicates, aluminates, and phosphates. There are several variations of the latter three of these types.
Nitrates are a major part offertilizers, so when we use fertilizers they get in the soil and from there to the underground water supply.The reason they usually get past the purification at the water plant is that nitrates are very soluble in water and very hard to separate
When there is too much phosphate in the water it causes algal blooms. When the decomposers try to break down the phosphate they use up all the oxygen, leaving none for the other organisms. when this happens all the organisms end up dying.
Because nitrogen and nitrates are not easily permanently bonded with other elements. As are for example, the silicates or the phosphates. Or even the oxides.
Try to stop phosphates and nitrates entering the water
Plant and algae growth increases
nitrates are fertalizer, chemical wastes, and pee and poo that atracts algea phosphates are dtergants that attract aglea
secondary treatment
Examples: potassium chloride, phosphates, nitrates.

Fertilizers are not acids; they are phosphates, nitrates,etc.
