The first is the choice of tank air pump, we know that the dissolved oxygen in the hot summer water is extremely important for ornamental fish, so how to choose and use a suit of fish tank oxygen system?

1. Appearance inspection

After to get the pump first depends on the outer packing is complete, or have to be pushed and obviously haven't got the trace of knock against on the next step, reason is that the rough handling in the process of transportation is likely to lead to pump some internal parts, screws, cup, loose, in areas such as the electromagnetic spring that is one of the factors that produce resonance and difficult to solve.

Inside the pump after electrify due to didn't answer the trachea, in no load condition and the outlet of the comprehensive factors, such as air flow will have a lot of noise, this is always the same regardless of the grade discretion, so this time we can use a finger on the outlet, turn out for a little while, carefully listen to the voice will have vibration, choose according to the size of the vibration noise.

2. Contact test

The socalled contact test, is to let the air pump itself of the foot and glass, desktop and other fixed rigid object contact, repeat the second step after electrification, observe whether the noise under contact is in the acceptable range.

3. Power selection

Aquatic animals box USES air pump (except of compressor), it is a few W basically, consume electric quantity is not high in comparison, choose a bit bigger as far as possible when so choose and buy, because most air pump has adjustable function. In the sufficient range, the air output to half the noise will be reduced a lot, if there is no adjustment function we can install a simple regulator valve in the middle of the pipe or even directly in the middle of the pipe tied a knot to control the air volume.

4. Selection of accessories

With the long-term use of air pump accessories include: water demon, air head, pneumatic bottom filter plate

So what kind of tank is suitable for water demon, what kind of tank is suitable for air head?

Here's a quick list from my experience:

For instance aquatic animals box has bottom sand, raise some small amount of small-sized fish (can breed) or admire the environment of shrimp, do below the premise that the law of microcirculation filtration changes water, can satisfy the requirement that maintains to water quality basically, and to small fish, small shrimp does not have physical harm.

If you like the big fish, the size of the cylinder and a lot of cases, then in this hot summer need to make sure that the dissolved oxygen in the water, because of the big fish eating to drain for water quality control system is a great test, to ensure the sufficient oxygen can ensure good bacteria such as nitrifying bacteria survive, the other for the fish to have sufficient oxygen. Water goblins should not be used at this time, because the water goblins are poor at refining the oxygen and cannot allow the oxygen to dissolve in the water to the maximum extent. The correct method is to choose and buy a 5W or more than the air pump, drive a good quality air disc or air stone, put the air disc at the bottom of the tank but do not contact the glass, 24 hours uninterrupted oxygen, in order to ensure the water quality.
