Stainless Steel Semicircle Frame

Why the sub-salt exceeds the standard? Ammonia nitrogen exceeds the standard? Hydrogen chloride exceeds the standard? This is because the dissolved oxygen in the water is not enough, the residual bait, excrement, and algae plant remains in the pond will be decomposed into such harmful substances.    Usually do not tu on at night (the concentration of dissolved oxygen on the surface of the water is high at night, at this time, the oxygen increase opportunity will cause the dissolved oxygen on the surface to escape into the gas, just like Coca-Cola shaking will outgas), rainy days and large days No power on (the surface water ph value will be significantly lower when it rains, and the aeration opportunity will promote water mixing, which will cause stress response).    And before the fish floated their heads, this harmful substance had already been caused. Subsequent application of aerators must comply with the 'three-in-two-stop' standard: tu on in the afteoon on a sunny day (promote the water circulation system to send the colorful dissolved oxygen on the surface to the bottom layer to reduce the lack of oxygen at the bottom of the pond), and the next day on cloudy and rainy days    Tu on in the moing, rainy, or when there is a sign of floating head, and then tu on in the middle of the night (when the left and right conditions occur, the dissolved oxygen in the pond is low, so an aerator must be used to China Solar Plastic Feeder increase the dissolved oxygen in the pond, so as to prevent the floating head from causing death due to insufficient oxygen ,China Solar Plastic Feeder ...ادامه مطلب
