How to make soft water for tropical fish breeding

There are two main methods of water softening:

The first is the chemical softening method, which is to add some agents to the water, so as to convert the calcium and magnesium ions in the water into insoluble compounds and precipitate them, such as lime softening method. There are also softeners such as trisodium phosphate, disodium hydrogen phosphate, etc. to soften water, this method is suitable for non-alkaline water, generally refers to the hardness of calcium in 75 175mg L or for water with high SiO2 content, the softening effect is better with this method.

There is also an ion exchange method, which generally uses sodium ion exchanger or hydrogen ion exchanger or hydrogen ion exchanger to soften hard water: that is, Na+ or H+ is used to replace Ca2+ and Mg2+ in the water, the concentration of Ca2+ and Mg2+ in the water is reduced, or even reduced to zero, so that the water is softened.

As for the reproduction of immortals, it can be mixed with pure water; treatment with ion exchange resins (ion exchangers); add grass mud pellets and peat to the tank; Add black water.

Natural is healthy, and I recommend that you don't use chemical methods to do it, as it may be harmful.

Keeping a water sprite in a small tank is good for breeding.

Quickly make soft water: plantain leaves or olive leaves soaked in water for 2-4 days, take out, the water quality can quickly soften a lot, and the color of the water will become yellow, very similar to the natural growth environment of angelfish, I used to use it often, and I feel that the effect is OK.

If you can't find these leaves, you can also buy softeners, which are available in aquarium stores, which are very common.

It is more convenient to have a water softener at home :)

Go buy lazy leaves or olive leaves and soak them for 2-4 days! ** On or at the fish market are bought!

For beginners in tropical fish farming, more than half of the deaths of new fish are caused by mistakes in overwatering. The first method: open the bag, first inject about one-tenth of the water in the tank into the bag, and then slowly add the water in the tank, and the time is controlled in half an hour after the ratio of water in the bag to the water in the tank reaches 1:

1。Then carefully remove the fish and put it in the tank. This method does not pollute the water in the tank, but the disadvantage is that some delicate fish still cannot adapt to the new water quality environment.

The second method: use the equipment to drop the water in the tank into the bag, and use a siphon to suck out the water in the bag and throw it away, this process can go through 2 hours, slowly turn the water in the bag into the water in the tank, and finally let the fish swim out of the bag and into the fish tank. Because in the process of long-distance transportation, fish will excrete waste and some shedding ** mucous membranes, which will promote the growth of bacteria and cause various diseases when they enter the tank.

In addition, the water in the original bag may carry bacteria, viruses and parasites in the original water body, so the water in the bag should be avoided from entering the tank, and some fish with strong resistance should be simply disinfected before putting it into the new fish tank.

1 Identification of male and female tropical fishTropical fish is an ornamental fish with a wide variety of species and a wide range of production areas. The identification of males and females varies depending on the type of fish. Here are some basic features for reference.

Cyprinid males tend to be brighter and richer than females, with slightly smaller bodies than females and less large bellies than females.

Most males of the family Lipid Cyprinidae are thin and small, and most females are hypertrophied, and the abdomen of females will be enlarged after egging.

The anal fin of ovoviviparous males develops into rod-like joints during the breeding period, which is a clear sign of male and female. Such as guppies, moonshine fish, etc. Most males have longer and more pointed dorsal and anal fins than females, brightly colored, and protruding foreheads.

Most males of the perch family have longer and sharper dorsal fins, anal fins, and tail fins than females, and their colors are brighter than those of females.

2 Selection of tropical breeding fishIn order to breed excellent tropical fish varieties with strong bodies and beautiful body colors, the most important thing is to select excellent individuals for mating.

Generally speaking, for the selection of breeding fish, male and female fish with large individuals, bright color, standard morphology, young and strong, and good gonadal development should be selected from the same species and same age fish.
