The semi-straw tank is more beautiful than the bare tank, and it is not troublesome, and its limited bottom sand is not enough to constitute the side effects of the sand tank. It seems that Crocker with a half straw is more suitable for ordinary players. Can feed a lot, but also save a lot of trouble in cleaning and changing water. Appropriate aquatic plants are helpful to the shy fish, Qicai.
First, the water filter? Water filters can be divided into many kinds according to their working principles and uses, but any water filter is composed of two parts:? Pumping device-an electric device based on the principle of water pump, which uses the power generated by it to drive the water in the water supply tank to flow and circulate. When sewage flows through the filtering equipment, the water quality is clarified through the physical and biological effects produced by filtering equipment with different properties. ? Filter materials-materials used to filter sewage, such as cotton filters, activated carbon, biochemical ceramics, biochemical balls, etc.
Suggestions for selecting water filters:
1. Upper water filter? Simple physical filtration, the motor (or submersible pump) located at the top of the feed barrel drives the turbine to pump water from the bottom of the barrel to the filter box, and the water flows back into the barrel after passing through the filter material? It is more suitable for small and medium-sized bare cans, and the noise will become louder after long-term use. It's best not to use it in a fish tank in the bedroom? 2. bottom water filter? Biological filtration: when the water pump pumps water from the diversion pipe buried under the bottom sand, it drives the water flow from the upper part of the bottom sand to the lower part, and at the same time drives the dirt in the tank to flow into the bottom sand, and decomposes the dirt with the help of biochemical bacteria attached to the sand surface, thus purifying the water quality? A very good biochemical filtration system, suitable for sand tanks and straw tanks, and works well with other filtration systems?
3. Biochemical cotton water filter? The buoyancy of air is used to drive water to flow. When water flows through the biochemical sponge, the dirt in the water is absorbed by the sponge and decomposed and purified by the biochemical bacteria on the sponge? It also plays a role in purifying water quality and boosting air. When filtering, the water flow is gentle, which is extremely suitable for raising miniature feeding tanks with bright colors and small stocking amount.
4. Built-in water filter? The whole system is located in water, and the submersible pump directly sucks water into the filter box connected to the pump. The filter box of the advanced system is equipped with a variety of filter materials? Simple and beautiful appearance, suitable for all kinds of feeding tanks, but the simple system has poor performance and is troublesome to clean. If your tank is full of fish, don't use it?
5. External water filter? The principle is similar to the built-in water filter, except that the whole system is located outside the water supply tank, and only the pumping pipe and outlet pipe are located in the water tank. Multiple filter materials make it have good performance? It is convenient to use and maintain, does not occupy the space in the feeding trough, but is expensive, so it is a good choice for large feeding troughs.
