Nitrobacteria should buy reliable dry powder in fish shop.

Yeast goes to the mall to buy pure yeast powder to make dough;

Replacing lactic acid bacteria with active yogurt;

Bacillus subtilis will use a pediatric digestive medicine bought from a pharmacy-"Mommy Love".

Then, clean the turtle tank filled with 100 liter of sun-dried water, put all the filters, filter cotton, glass rings, activated carbon (or medical stone), water, water pump, heating rods, sand, stones, grass and other things into the tank or filter tank for disinfection with potassium permanganate, just soak 20 grams of potassium permanganate for half an hour, and then put them into the turtle tank.

Then pour the dried water into the turtle tank. At this time, the 15g dry powder nitrifying bacteria bought from the fish shop are poured into the tank; Then, a spoonful of pure yeast powder, a spoonful of active yogurt and a small bag of Bacillus subtilis are put into a tank to be dissolved in water, the clarified part is poured back into the tank, and the remaining residue is poured into a filter tank.

The jar is foggy at this time, and it will be clear in a few days;

Next, raise some small fish first! They are pioneers, remember to disinfect the turtle tank before * * to avoid carrying germs in the tank; After that, feed it twice a day, and the food must be eaten within 1 to 2 minutes each time. Then wait. If the water quality is turbid the next day, change some water appropriately, and then reduce the feeding appropriately. Live like this for 3 days;

On the fourth day, if the water quality becomes unusually clear (sometimes it will be clear the next day, but you still have to wait until the fourth day to operate), then the water will be lifted soon! At this time, we should continue to test the strain capacity of microbial filtration system. Just double the feed. I have been waiting for 3 days; If there is a little turbidity during the period, observe carefully, as long as there is no foul smell, there is no need to change water; On the seventh day, if the water quality is still clear, we can invite the tortoise into the jar. First, change the water, put one or two turtles, feed a small amount, observe for 3 or 4 days, and then continue to put other turtles, and the food intake will gradually increase; In this way, we can change the water from 1/5 to 1/4 every week in the future, and we can get long-term and stable good water! At this point, we have completed the construction of "nitrification system", which can be stable for a long time by changing water every week.

However, there are still some harmful substances in such water, that is, nitrates, which need to be diluted by changing water regularly to keep the water stable.

How can I not change water for a long time? Continue: Using the sensitive reaction of algae to light, set up an independent filter pool in the filter equipment and cooperate with appropriate illumination to cultivate brown algae, green algae and even black algae in large quantities;

2) Or plant a large number of aquatic plants in the filter pond, including duckweed, Sophora japonica and even water hyacinth; These large amounts of algae or plants will basically eliminate nitrate, which is the last process of water conservation. In this way, the large circulation system of oxidation, decomposition, denitrification and reduction of water in the whole turtle tank is basically completed. Initially, the water in the water tank becomes a water system with self-purification ability. Basically, the construction of the ecological circulation filtration system of the nail fish tank without changing water for a long time has been completed.

It should be noted that not changing water for a long time is not the best way to raise turtles, and changing water regularly is an indispensable means to maintain the ecological stability of turtle tanks.

note:

1, where the flora lives: the glass ring should preferably exceed 3% of the total volume;

2. Oxygen that the flora breathes: at least one air pump is indispensable;

3, the food of the flora: there must be at least one strong fish in the tank that is not afraid of death; 3|%

4. Water flow in the place where the flora lives: 100 liters of water should have a water pump with a flow rate of 600 liters/hour;

5. The suitable temperature for the flora to live is100L, and the heating rod100W to150W.
