It is best not to keep goldfish in solar water.
Solar water is stagnant water. After repeated exposure to the sun, it is easy to breed bacteria. After testing, the solar water heater water contains nitrite and bacteria exceeds the standard. To prevent goldfish from getting sick, it is recommended not to use indoor water for breeding.
The predecessors of goldfish breeding have long had the experience of "raising fish first, raising water", which shows that water quality will directly affect normal growth and development of goldfish. The purpose of water changing is to remove dirt (waste, fish feces, food scraps and old impurities) in the water, keep the water clean, adjust the water temperature and to increase oxygen in the water, thereby stimulating growth and development. of inred isson. If you want to raise goldfish well, you must have a prior understanding of fish farming water:
1. New water refers to tap water that has just been released, which is the most ideal water for fish farming. It should be noted, however, that the water temperature is often very different from the water temperature of fish ponds (tanks) and that temperature adjustment treatment is necessary (in some areas the water tap containing a lot of chlorine must be dechlorinated).
2. Waste water is the dirty water containing feces and dirt at the bottom of the fish pond (tank). Including the pool feed water (tank) which has not been changed for a long time. This has a great impact on the growth of fish.
3. Old water
is the general name for clean, tender green, green, old green or green-brown water in fish ponds (reservoirirs). Among them, soft green water is the best. There are more green algae floating in the old water, which is also a good supplementary food for goldfish. This type of water contains less putrefactive and decomposed organic matter and more dissolved oxygen. Fish are often raised in clean, tender green water. Bred fish have a stronger appetite, strong body, bright color and rapid development.
4. Return to clear water
If you find that the old green water in the original pool (tank) suddenly turns into clear water and many green algae settle at the bottom of the tank , this phenomenon is called return to clear water. This type of water can easily cause disease in fish and should be completely replaced.
Usually water for solar power comes from tap water because the water company has already killed most of the organsnisms present in the water and it contains high-capacity alum, which does not have the conditions for fish to survive. and other aquatic organisms. It is recommended to place the solar water in the sun for 2 hours. (Note: Do not change all the water when changing water, only 1/3 is enough) For reference only! Thank you
