petnet reminds that water is the most important and basic condition for fish to survive, and the quality of water quality directly affects the health of fish. The various factors in the water body directly affect the quality of water quality. Different species of fish have different requirements for water quality, so the quality of water quality is relative.

First, chlorine preparations

The water plant is in Before the water supply, chlorine preparations will be put into the water to kill microorganisms in the water. In order to ensure that each user's outlet maintains a certain concentration, the amount of chlorine input is quite large. Chlorine preparations are harmless to humans but to fish. However, it has a great toxic effect, so the tap water cannot be directly used to raise fish and must be disposed of.

Disposal method:

1 The conservative method is to use an open basin with tap water to dry for 24 hours, and let the chlorine gas by itself volatilize.

2 Sodium thiosulfate (Hippo), commonly known as big soda, is a square granular transparent crystal. It is chemically dechlorinated in water, which has a certain effect and is cheap.

3 There are various dechlorination agents on the market, which have good dechlorination effect and are slightly expensive.

Second, PH and hardness

PH (pH) and hardness are two important factors that affect the growth and development of fish. The raised ornamental fish come from different countries and regions, and the requirements for pH and hardness are different, even very different. Therefore, it is necessary to adjust the pH and hardness.

Unsuitable PH can lead to the following symptoms: Unsuitable hardness can lead to the following symptoms: 1. Physiological dysfunction; 1. Egg-laying dysfunction; 2. Egg-laying dysfunction; Decreased immunity, multiple diseases; 4 dysfunction of osmotic pressure adjustment, easy dehydration or edema; 4 abnormal secretion of mucus on the body surface. 5 Abnormal secretion of mucus on the body surface; 6 Rapid changes in PH value can lead to sudden death of fish.

The principle of acidity and alkalinity: the different content ratios of hydrogen ions [H?] and hydroxide ions [OH?] in water form the Acidity and alkalinity of water.

To adjust the pH of water, you can use acid-base regulators, which are generally available in the ornamental aquarium market. Alkaline buffer. You can buy it according to your actual needs. It should be noted that in the process of adjusting the pH, each adjustment should not exceed plus or minus 0.2PH to prevent the fish from causing acid-base shock due to acid-base mutation.

The water quality of Luohan fish is neutral and alkaline. The ideal water quality is 6.87.2 pH, but it can live normally at around 67.8, beyond this range will affect growth. To check pH, you can buy a pH-checking potion or detector at a water cluster store. If the pH is high, you can add phosphoric acid, sinking wood, and water softener resin to slowly lower the pH. If the pH is too low, you can add coral sand to slowly increase the pH. In the process of adjusting pH, do not exceed plus or minus 0.2PH each time to avoid acid-base shock disease in fish due to acid-base mutation.
