Keep a few fish, but the water is not clear, the change of water, add oxygen pump, and nitrifying bacteria can
May be the filtration system not perfect Oh, to a suitable collocation cylinder filter ~ can be Taobao search service our Kyrgyzstan and India we will contact the Jiyin professional for you collocation set for you perfect filtering system Oh
Filter and oxygen. Wash the filter cotton three days;Feed as little as possible. It's cold now, once a day is enough;Every day the fish at the bottom of the tank is pumped out (with a sand washing device), the time in the morning, by the way, change the water 1/4;Do not use any liquid in the water, including nitrobacteria.About 3 weeks to a month, to establish the circulatory system. The water becomes crystal clear.Landlord remember a word, fish to meditation, do not worry.
Water is always not clear, the reason is that the turbidity is faster than the filtration system. Turbidity is generated mainly from the following sources:1, residual bait decay2, fish and other aquatic creatures, fecal decay3, fish surface secretions4, aquatic plant metabolism products decay5, dust, etc.Changing water is a way of regulating the table, but not a permanent cure, and if new water and old water vary greatly, it will stimulate the secretion of fish's surface. The air pump is used for oxygen increasing and has nothing to do with the turbidity. Although not directly eliminate turbidity bacteria, but it is a correct way to improve water quality, but also:1, reduce the feeding density2, reduce feed intake3, keep good physical and chemical indexes of water quality4, timely pruning of aquatic plants (if any)5. Strengthen the filtration system
