Based on a standard marine aquarium with leather corals, the data on the suitable aquarium size may differ for other biotope compositions.

The goal, more performance from less space. Comline® components meet these requirements and the visual harmony of the aquarium is maintained. It is no longer necessary to hide technical equipment in the aquarium; instead, it forms an integral part of it. The system is highly effective; all organic pollutants are removed from the environment directly, while the path the water has to cover is short and direct. The risk of leakage is almost zero. The highly efficient technology enables reduction of the volume of the internal equipment, as well as significantly reducing the energy consumption .\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tComline® DOC Skimmer 9004\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tThe Comline® DOC Skimmer 9004 is designed for use in seawater up to 250 liters (66 US gal.). It operates according to the TUNZE® flash skimming principle and acquires the water through an efficient surface suction with a surface film removal, and can therefore also be used as a \"stand-alone\" solution in the aquarium.

On the surface of the air bubbles, pollutants such as protein, cellulose, dead cells, etc. are adsorbed immediately, the air bubbles are very fine, with a diameter between .1 and .3 mm (.004\" - .012\"). The water \/ air mixture expands and stabilizes in the skimmer cup reactor, the water returns to the aquarium, and the protein-loaded air bubbles spill over into the skimmer cup. The patented anti-overfoaming system intermediate chamber prevents the skimmer from overfoaming and controls the skimmer performance, depending on the water level and organic load.\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tThe particularly high efficiency of the flash skimming principle, compared to large skimmers with long contact time, is obtained because the substances adsorbed by the air bubbles are not released again, thus they don't return to the aquarium water.\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e","brand":"Tunze","offers":[{"title":"Default Title","offer_id":41721734234158,"sku":"T9004_001","price":259.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/4276\/8686\/files\/12966.jpg?v=1765980827","url":"https:\/\/mattscorals.com\/products\/tunze-doc-skimmer-9004-dc","provider":"Matt's Corals","version":"1.0","type":"link"}
