The OFA water surface extractor is a very effective appliance to be used in any marine and freshwater tank. The appliance makes the water clear and with low surface tension. This enables a free gas exchange. As in the nature, the balance of gases is achieved. The biochemical oxygen demand in the tank is met and the bacterial filter structure assists the ideal oxidation of organic substances. The lifetime of the filter is doubled and the sedimentation of mull is avoided. The open, low-tension water surface increases the incidence of light and improves the photosynthesis. The appliance can be used with any suction filter of 30 - 1200 l/h. There is an automatic level adjustment of up to 60 mm. When feeding the fish, the suction effect at the water surface can be cut off.The OFA water surface extractor is available in 3 versions:
