Ordinary fish tanks are rectangular, so the calculation of the volume is relatively simple, only need to multiply the length, width and height. However, it should be noted that fish tanks are generally not filled with water, so the volume of water should be calculated according to the depth of water, which is not the same as the volume of fish tanks. If it is some irregular fish tank, it is almost impossible to calculate the volume, can only weigh first, then weigh after filling water, according to the weight of water to calculate the volume.
1. Water quality maintenance: a large fish tank is easier to maintain water quality, because the volume of water is large, the speed of bad water will slow down, thus delaying the cycle of water change. And if there is filtration, the ecosystem of the fish tank can be better maintained, which is also very helpful to the health of the fish.
2. Raising large fish: The general small tank cannot raise large fish. Because the activity space is limited and the dissolved oxygen in the water body is low, it is often difficult to raise large fish. But the big fish tank raises the big fish naturally not to mention, even may also the group raises or mixes raises, several kinds of fish in the fish tank, also can increase its ornamental.
3. Stable wave-making: If you want to generate water flow in the fish tank, you generally need a wave-making machine, which has different effects on fish tanks of different specifications. Smaller fish tanks will have larger waves, and even lead to water overflow, and if the fish tank is large, the wave machine will not produce waves.
