Designed for aquarists keeping fish, shrimp and plants who want to lower pH and KH gradually without chemical buffers. The cones are placed directly in the tank, so they suit both beginners and those running biotope or planted setups.
Why it matters
- Gradual pH reduction: the cones acidify water down to around 6.8 or lower.
- Tannins and humic acids: the supplier states these compounds have antibacterial and antifungal properties and give the water a natural amber tint.
- Support for stressed fish: according to the supplier, they help fish recover after stress, transport or illness.
- Natural microfauna: they create conditions in which microorganisms, a food source for fry and shrimp, can develop.

What it works with
The cones suit community and single-species tanks with soft water, especially aquariums with betta, neon tetras, killifish and shrimp. In very soft water the pH-lowering effect may be stronger, so regular testing of parameters is advisable. Because the cones are natural, size and weight vary between pieces, so the number of cones in each pack varies slightly.

They usually work for about 2 to 4 weeks. In very soft water the pH-lowering effect can be stronger, so it is worth testing your water parameters regularly.
The manufacturer especially recommends them for tanks with bettas, neon tetras, kribs and shrimp. They can also slightly lower KH, which may suit tropical fish that prefer softer water.
A pack typically contains about 10 cones (plus or minus 2 pieces), and the manufacturer usually packs between 10 and 12 pieces.
