Description

[Detailed explanation of the invention] (Field of industrial application) This invention facilitates the growth of aquatic plants by placing it at the bottom of the aquarium to circulate water within the substrate, keep the substrate warm, and inject fertilizer into the substrate. It relates to equipment for

(Conventional technology) With conventional bottom filters, when fertilizer is added to the substrate, the fertilizer is sucked out into the water as the water circulates, polluting the water, and the water becomes eutrophic, causing moss to grow and spoiling aquatic plants. I often end up.

Furthermore, conventional linear or plate-shaped electric heaters have the disadvantage that the bottom floor becomes too warm.

Conventionally, whenever the effect of fertilizer wears off, a series of tasks must be repeated, such as pulling out the aquatic plants, washing the gravel, removing old fertilizer, adding new fertilizer, and replanting the aquatic plants.

There are also liquid fertilizers that can be added to water, but since they eutrophicate the water, they tend to grow moss, so experience is required to know how to use them.

(Problem to be solved by the invention) This invention was devised in order to eliminate these drawbacks and make it possible to easily grow aquatic plants with only a little management without requiring any skill. be.

(Means for solving the problem) The structure will be explained below with reference to the drawings. (There are no restrictions) (the bottom plate may be omitted)
A bottom box 1 with small holes 5 of about 1 to 1.5 mm in diameter made at intervals of about 1 cm throughout the top surface.

(b) A pipe insertion port 3 leading to the inside of the bottom box 1 is provided at the corner of the bottom box 1, and a hollow pipe 4 is inserted therein.
Insert.

(c) Attach a hollow pipe 2 to the top of the bottom box 1 so that it spreads uniformly over the top of the bottom box 1, and make a small hole 8 with a diameter of about 1 to 1.5 mm about 5 cm in the top of the hollow pipe 2. Space them in a row.

(d) Pipe insertion ports 6 are provided at both ends of the hollow pipe 2, and the hollow pipe 7 is fitted into either end. (The hollow pipe 7 is bent at a right angle near the drain port 9.) (Function) Since the proposed structure is as described above, when using this, the length of the hollow pipe 4 is the same as the length of the water in the tank. Adjust so that the fertilizer inlet 10 is about 2 cm above the water surface.

The hollow pipe 7 has a drain port 9 located below the water surface.

Next, a small submersible pump 1 with a perforated pipe 12 attached to the water intake port 11 and a sponge 13 inserted therein.
Attach the drain port 15 of No. 4 to the pipe insertion port 6.

Place the substrate device for growing aquatic plants in an aquarium constructed as above on the bottom of the aquarium, cover it with gravel of about 2 to 3 mm in size to a thickness of 5 to 7 cm, and then water it. When aquatic plants are planted in the gravel and the small submersible pump 14 is activated, the water filtered through the sponge 13 is sent into the hollow pipe 2 by the small submersible pump 14, and some water flows into the small hole 8.
Most of the water is ejected into the gravel through the hollow pipe 7 and drained from the drain port 9.

This is left until the water becomes clear, and once the water becomes clear, fertilizer is injected through the fertilizer inlet 10 to complete the process.

(Example) In implementing the present invention, the following can be done.

(a) The small hole 5 has a linear gap.

(b) The small hole 8 has a linear gap.

(c) Items that do not have small holes 8.

(Effect of idea) The present invention has the following effects.

(a) By circulating water in the hollow pipe 2, the substrate is kept warm and the temperature difference between the stems, leaves and roots is eliminated. Additionally, the water in the tank keeps it warm so it doesn't get too warm.

(b) A small amount of water is squirted into the gravel from the small holes 8 to supply oxygen to the roots and prevent root rot.

(c) Old fertilizer can be removed by injecting fertilizer through the hollow pipe 4 and draining it by attaching a hose to the hollow pipe 4. Therefore, replacing fertilizer becomes easy.

(d) By storing fertilizer inside the bottom box 1, nutrients are supplied directly to the roots, making it difficult for the water to become eutrophic and preventing the growth of moss.
