Protein SkimmersProtein Skimmers

Protein Skimmers

Also known as, Foam Fractionators, Protein Skimmers help remove dissolved Organic Contaminants, including Proteins, Amino Acids, Phenol Oils and other Yellowing Compounds, from the Marine Aquarium Water, before they start decomposing into Ammonia, Nitrite, and other toxins. As a result, of this water cleaning, the incidence of harmful floating Bacteria, Yellow Discoloration of aquarium water, Nitrate & Phosphate build up, and Slime Algae, is significantly reduced.

Based on the principle of Surface Tension, and employing a similar methodology as that of Mechanical Filtration, these Protein Skimmers allow Oxygen bubbles to pass through a column of dirty aquarium water. In the process, friction takes place between Oxygen bubbles and the Organic Waste Molecules, especially Protein, present in the water. As a result, the Waste Molecules in the water get ionic charges, which stick to the Oxygen bubbles to be carried out to the Collection Container. This whole process of Protein Skimmers supports the Biological Filter of an aquarium and leaves the Marine Aquarium Water clean and aerated. Fresh Marine brings to you a wide collection of different type of Protein Skimmers from different brands. Lets take a look.

Combination Protein Skimmer. Combination Protein Skimmers usually include Protein Skimmers coupled with some other Aquarium add on, such as, a Filter, or a Refugium to name some. Therefore, these Combination Protein Skimmers offer dual-purpose equipment in one, for your Marine Aquarium.
