How to raise fish without changing water

Fish farming for water is a very troublesome thing, when to change the water, is to change all, or just general? These problems perplex many fish farmers. How can fish culture not change water?

1. Add nitrifying bacteria regularly

Usually to regularly add nitrifying bacteria to the tank, nitrifying bacteria will engulf and decompose organic matter and nitrate. Make the water in the fish tank cool and transparent, and there will be no gray. It will also reduce the content of nitrate, making the water quality more suitable for fish survival. But what makes the nitrifying bacteria survive is the filter material in the filter cartridge and the bottom sand, so we'd better choose the bottom sand to use aquatic grass mud or ceramsite, which are covered with enough cracks.

Second, clean the filter cartridge regularly

If you do not change the water, you must rinse the filter cartridge regularly, do not use chemicals such as washing powder, and it is best to use multi-gap filter materials. Because the bottom sand will pulverize and flow into the filter cylinder with fish and shrimp biological feces over time, if the filter cartridge is blocked for a long time, it will lead to the death of a large number of nitrifying bacteria previously added, then the nitrate content in the fish tank will rise. acidic water quality will kill the fish.

Raising water plants in a fish tank

Experienced friends should put a few aquatic plants in the fish tank, because the aquatic plants will absorb carbon dioxide to produce oxygen during their growth, which will increase the oxygen content of the whole fish tank and make the fish grow healthier. And the decay of the old leaves of aquatic plants will turn the water into what we commonly call "yellow water", which is more suitable for the growth of fish, which is not only convenient but also beautiful.

Fish farming without changing water can be achieved, as long as you do the above three points, you can save such a troublesome thing.
