In the filter tank, pay attention to:
(1) The germicidal lamp mainly relies on ultraviolet light to play a germicidal role, and ultraviolet light is also harmful to the human body, so pay attention to the use of germicidal lamp can not be directly exposed to the human skin, especially the eyes (dozens of watts to see a few seconds of nothing, pro test), so it is generally placed in the filter tank and then opened.
(2) Avoid using in the master tank, directly irradiating the body surface of the fish, affecting the normal growth of the fish. When used, it should be used in the filter tank as far as possible, and as far away from the filter material as possible, and there should be a barrier between the filter material, so that its loss of nitrifying bacteria is minimized.
(3) It can not be used continuously for a long time every day to avoid causing the imperfect nitrification system of the aquarium water body. It is easy to kill fish when stopped. Usually two hours a day. There is also a germicidal lamp that is built into the water pipe of the filter pump, which is not related to the fish tank.
