Nitrate and phosphate are nutrients and can only be removed by water changes with a Reverse Osmosis or RODI Filter System or by having some organism consume it. In most aquariums without plants as competitors, algae will consume the nitrate and phosphate resulting in a tank full of unwanted and unsightly algae. In a great deal of  marine aquariums cyanobacteria, which grows like a red to black carpet over the entire aquarium, will consume the nitrate and phosphate. To grow algae and bacteria you need carbon, nitrogen (nitrate) and phosphorus (phosphate). Studies show that many man...

The worlds Coral reefs have formed through the mineral deposits of billions of small invertebrate animals, called coral polyps. All of these polyps survive via colonies, which are made up of one to many thousands of individuals. They are able to construct homes made from calcium carbonate, similar to the bones in our body. They can retract themselves into their little homes when attacked by predators. Over millions of years, these animals have been able to create vast underwater mountains which we call coral reefs.

After having caught a prey, their cnidocytes release tiny poisonous harpoons. These powerful...
