The gas-flushing device of tropical fish basically is device full oxygen, when be not being had as biology because of tropical fish
Without quarter consuming oxygen, small aquarium cannot satisfy their need. Want so seasonable
Additional oxygen. Theoretic tell, every liter water can raise the small-sized fish under 3 3cm; Or 1.5
The medium-sized fish under 6cm. Or the large fish under 0.5 10cm and enraging normally
Await next filling oxygen. But if enraging the weather of depress, below the situation that measures inadequacy like oxygen of dissolve of plum rains day
, need to fill oxygen. And want 24 hours to keep, in case fish strangle.

Aquatic animals box is raised view and admire a fish, often need to add aerate equipment, undertake full to water system
Angry, its action raises want to have:

It is the dissolved oxygen quantity in can adding water, carry oxygen to each corner,
Because oxygen is insufficient,avoid and produce a harm to fish. Mix to box of briny aquatic animals especially did not grow
Kind the water put oneself in another's position of aquatic is more significant.

2 be make through aerating the atmospheric pressure in water increases, make water system produces wave motion, in order to achieve
The purpose of the harmful gas such as hydrogen of the carbon dioxide of cleared and deliquescent Yu Shuizhong, vulcanization, arrive since clean
Change the intention of water quality.

3 it is to aerate can make water system generates flow, avoid water of the fluctuation inside aquatic animals box lukewarm abhorrent
phenomenon. When winter uses attemperatior, the convection action of water makes heat energy even the ground
Leave dispersedly.

4 it is the addition as a result of the oxygen in water, make the mobile aggravate of good oxygen bacterium, add thereby
Fast in water of harmful material decompose) improve water annulus condition.

5 because the gas of pump input forms bleb,be from exhaust mouth ejective, fall by cistern
The layer hangs up, strengthen aquatic animals case move feeling, raised aquatic animals chest view and admire value. Fill
Air equipment sort is more, the aquatic animals box with box of large aquatic animals or more amount can use empty atmospheric pressure
Shrink the pump air feed with machine or high-power, big sendout, medium or small aquatic animals box or amount are not much
Person, can use appropriative dynamoelectric miniature air compresses pump aspirated.

Pump is defeated by air course ceaselessly tracheal, in sending a person water by exhaust mouth. Average platoon
Gas mouth is arenaceous filter stone (gas stone) , petty empty bleb becomes air after arenaceous filter ejective,
The oxygen dissolve that makes air medium at water.

Be defeated tracheal but refute is received or ramose divide bronchus into many, in order to join one or more
Gas mouth. When choosing pump, according to the oxygen demand decision of the norms of aquatic animals box, amount, fish
