The most commonly found cyanotoxins in the U.S. are microcystins, cylindrospermopsin, anatoxins and saxitoxins. During the oxidation process, hydrogen-peroxide (H2O2) will break down into water (H2O) and pure oxygen (O2). Some freshwater cyanobacterial blooms or cyanoHABs are able to produce highly potent toxins, known as cyanotoxins. During either procedure, it is a good idea to remove the bacteria as it appears. Freshwater Biology. Many freshwater tropical fish are great algae eaters in their own rite. They perform many roles that are vital to our aquatic communities, by being a food source and producing oxygen. They can also be found in estuarine and marine waters in the U.S. Cyanobacteria are often confused with green algae, because both can produce dense mats that can impede activities like swimming and fishing, and may cause odor problems and oxygen depletion; however, unlike cyanobacteria, green algae are not generally thought to produce toxins. This is one resilient life form, but why has it been so successful? Do they stay in the tank safely or have to be removed to another tank ?
