Natural driftwood collected from the river! I've gathered driftwood that seems suitable for use in my home aquarium, and I've been storing it after removing tannins and sinking it. I'm listing driftwood that I don't think I'll be using in the future as my stock has increased. The driftwood has been processed through the steps ① to ⑤ shown in the photos, and boiling has been done 2-3 times depending on the size of the driftwood♪ This driftwood has a beautiful arch and weighs just under 2kg, providing a solid sense of stability. When laying it horizontally, you can adjust the angle with gravel or sand to create a dynamic, three-dimensional layout with a single, powerful horn-like structure. Great as a climbing perch or basking spot for reptiles, or as material for creating shelters! In aquariums, it can be the centerpiece of a layout, taking advantage of its size, stability, and arch! It also provides ample surface area for attaching plants, allowing you to enjoy a layout in your favorite style♪ This is a versatile item with many possibilities♪ (´▽｀) ※ The listing includes only the driftwood. ٩( ᐛ )و【Notes】٩( ᐛ )و ① I believe it can be used for pets such as freshwater fish tanks and reptile tanks. However, the possibility of it affecting the animals is not zero, so please perform appropriate processing and use it at your own risk. Also, please understand that it is a natural material and may have imperfections or unavoidable dirt. ② Although the driftwood has been treated to remove tannins, it is not in a state where tannins will not leach out completely. The title "Tannin-treated" means that steps ② and ④ of the processing have been performed. Tannins may leach out more than expected depending on the water quality, water temperature, and the duration of submersion. If you are concerned about black water, please use a carbon filter or check the degree of tannin release beforehand before introducing it into the aquarium. ③ The driftwood will be shipped in a dry state, so it will take some time to sink, but I have confirmed that it sinks during the tannin removal process. ④ If there is no box that fits the shape of the driftwood, I may use a used cardboard box. I will not reuse boxes that are too dirty or tattered, so I would appreciate your understanding. If you would like additional photos, sanding, or an additional 1-2 hours of boiling, please feel free to consult with me before shipping, as I can accommodate requests within a reasonable range♪ I may not be able to fulfill all requests due to work and other scheduling constraints, but I will do my best to accommodate them. I look forward to hearing from you m(_ _)m
