When raising seawater fish, you must understand that the hardness and pH of the seawater have a dynamic slow-flushing system, which can maintain the water quality of the seawater. When the pH value of the seawater drops to 8.0, you may consider using methods to compensate for carbon dioxide. To maintain the safety of the slow flushing technology of water quality, there are two ways to compensate for carbon dioxide in seawater, which are briefly introduced below.
(1) Saltwater fish aquarium: The specifications of the saltwater fish aquarium are larger than those of the freshwater aquarium. It has more water capacity and the height of the aquarium is also higher. The specifications of aquariums for home inspection include: 70 x 35 x 45/cm, 130 x 55 x 65 cm, 160 x 65 x 65/cm, and 180 x 65 x 70 cm.
The specifications of exhibition aquariums are: 150 x 60 x 90 cm, 200 x 60 x 90 cm, 300 x 90 x 90 cm, etc. The materials of saltwater fish aquariums mostly use glass with a thickness of more than 10 mm, with rich-color gray, black or brown silica gel as the adhesive. Transparent silicone is occasionally damaged by algae or other organisms, causing the glass to lose stickiness.
A PVC pipe network needs to be laid at the bottom of the aquarium. There are evenly spaced meshes or slits on the plastic pipes. The pipe network is connected to two mechanical pumps of the same specifications that are relatively swaying. Put a filter plate with round holes on top of the pipe net, then lay a layer of plastic mesh, and finally put coarse sand and fine sand on top. In this way, a device in the aquarium that simulates the ebb and flow of natural seawater is completed.
The two mechanical pumps are connected to a timing switch. When the mechanical pump is working, seawater is pumped into the water pump from the pipe network at the bottom of the box, and then flows out from the water pump, creating a vibrating artificial seawater.
Generally, the timed switching can be set to 6 hours. One water pump is turned on every 6 hours, and the other water pump is turned off at the same time. The artificial seawater in the aquarium will vibrate alternately every 6 hours. Goal, this is what makes a saltwater aquarium special. The efficiency of these two mechanical pumps has certain requirements. The water pumping capacity of the mechanical pump is required to reach the seawater in the aquarium circulating 4-6 times per hour.
(2) Circulation filtration equipment: The filtration equipment in seawater aquariums is divided into two types: inside the box and outside the box, and outside-the-box filters are generally used. The filter outside the box can be largeIt can be small and can be placed in a vertical cabinet at the base of the aquarium or placed on either side of the aquarium. The filtration system uses a mechanical pump and is required to circulate all circulating water 2-3 times per hour.
(3) Lighting equipment: Small aquarium lighting equipment includes metal halide lamps, fluorescent lamps, mercury lamps and coral lamps. Equipped with lamps of different specifications according to the length of the aquarium, place them at the tip of the aquarium, preferably without encountering sea water, or hang them 40 cm above the aquarium. The optimal lighting time is 8-10 hours a day.
The power of metal halide lamps is 150W and 250W. It can create strong light, medium light and low light in the aquarium. It is the most promising lamp for saltwater fish aquariums. Fluorescent lights have better brilliance, and they can create medium light and low light in the aquarium. The power of mercury lamps includes 80W, 125W, 250W, 400W, etc., and they are often hung above the aquarium.
Coral lamp is a kind of light suitable for seawater invertebrates. It is divided into blue light and fiber optic light. It can reduce the color of corals and other invertebrates, and the observation effect is very good.
