fish tank is yellow but clear. It is possible that the water turned yellow after the feed was dissolved. It is also possible that there is sunken wood in the fish tank, which will also make the water yellow. In addition, if the water is not changed for a long time, the water quality will be aging and yellowing. For different situations, there are usually different ways to deal with, if it is the problem of feed, it is necessary to change the feed in time. If it is a problem of sunken wood, you can consider fishing it out. If it is a water quality problem, the water needs to be changed regularly.
1, trapped water: usually the water used for fish farming is tap water, want to improve this water quality, the first thing to do is trapped water. There are many ways to trap water, usually choose the way of drying, put the water into a basin, put it in a sunny place for a few days, so that the residual chlorine in the water will dissipate, eliminating the harm to fish.
2. Bacteria culture: If it is the water for the first fish culture, bacteria culture must be carried out. Nitrifying bacteria are needed in the water to complete the ecological cycle. The method of cultivating nitrifying bacteria is very simple. Pour in the right amount of raw materials every week. In the process of cultivating bacteria, the water will become turbid first and then clear again, so there is no problem.
3. Change the water: In order to maintain the water quality, change the water regularly. It is usually necessary to change once a week, about one fifth each time, not more than one third at most. Changing water too often or too much water can easily stimulate the fish and affect its survival.
