Upon application of Nualgi Aquarium, the Nano Silica base carries nutrients to Diatom Algae which start to multiply, consuming N and P, robbing the nuisance algae. Diatoms release O2 & consume CO2, thus increasing the dissolved oxygen levels and helps aerobic bacteria break down organic matter. As this occurs, zooplankton grow by consuming the Diatoms, and finally, zooplankton get consumed by fish and coral because that is their favorite live food. Hooray for free fish food!
