Silica testing in aquariums

Soluble silica molecules are important to aquaculture because they influence (and limit) the growth of diatoms. While diatoms consume CO2 and release pure oxygen (improving oxygen concentration), making your water clearer and your fish and coral healthier, it is important to limit the growth of diatoms. Silica also improves the health and growth of organisms such as sponges and mollusks.
