Nitrogen and Magnesium are the main élements forming chlorophyll.
Chlorophyll reflect green light spectrum. (side note) Too much
nitrogen will find it's way through the soil and to the water. Too
much nitrogen in the water will encourage formation of algae. While
algae will produce oxygen while alive...when that algae completes it's
cycle and therefore dies, it finds it's way to the bottom. There
bacteria will start decomposing matter and in doing so consume oxygen
in the water. As oxygen levels in the water decrease, it sometimes
gets to a point where fish have a difficult time breathing and dye.

Growing grass and keeping it green...needs a little advice.
