WB-50 outdoor stainless steel pond filter

Large outdoor ponds can refer to this video to install filters. Pond water requires a filtration cycle to remove solid waste from the water and cultivate beneficial nitrifying bacteria. Nitrifying bacteria can decompose ammonia nitrogen in water. Outdoor ponds are easy to breed green algae, and UV germicidal lamps can effectively kill bacteria and green algae. If your pond is now green, cloudy, and smelly, this style of filter is recommended. For more information, please refer to the link:
