Nitrates are ions that are commonly found in aquariums if the water is not cleaned and filtered regularly. Nitrates come from nitrites. In turn, nitrites come from ammonia, which is produced by decomposing biological wastes and spoiled uneaten food.
When left to stay in aquarium water, high levels of nitrates greatly affect the health of fish, corals and plants
in a very bad way. Nitrates cause oxygen levels to decrease. As a result, fish will have a hard time breathing, which will make them exert extra effort that can agitate their gills. Corals will not properly form their exoskeletons and plants will not thrive well.
To make sure that your aquarium is free of nitrates, you'll have to use the Kent Marine Nitrate Sponge from Pet Store
. This product is a zeolitic filter medium that works in a couple of direct ways. The first one is that it absorbs ammonia in the water. The second one is that it encourages the process of anaerobic de-nitrification through a biological process, thanks to its porous and granular texture.
The Kent Marine Nitrate Sponge can be used with freshwater and saltwater tanks. It is safe to use in direct contact with the water because it does not release back the ammonia, and it does not absorb nutrients.
