Yamitsu have been manufacturing Algae Masters in Great Britain since 1990. Their unique specification and design ensures a high efficiency unit at an affordable price. They are made from UV stabilised materials to ensure a longer life and incorporate turbulators to enhance the unit’s performance. Large inlet and exhaust ports make them suitable for a wide range of applications. Single tube units are available in 11, 15, 25, 30 and 55 watts. Twin units are available in 30, 50, 60, and 110 watts. It is recommended that Algae Masters should be installed using solid solvent weld pipe. However, all our units come complete with free (glue in) hosetails enabling them to be connected to ½”, ¾”, 1”,1¼” and 1½” flexible pipe. It will also fit most popular 1½”household solvent weld waste and pressure pipes. Also in case of little accidents we carry the full range of spares such as bodys , electrics quarts etc .Work on 10 watts per thousand gallons in part shade , the more the sun the more you will need to increase this .All other models after 11watt have inlets pointing the same way.
