This 4 g pack of Kruger Meier BlackWater Drop black alder cones is intended for aquarists who want to soften water and lower pH without adding chemicals. The cones can be placed directly in the tank, which makes them a simple option for tropical community setups and planted or biotope aquariums.
Why it matters
- Lowers pH naturally, to around 6.8 or below according to the manufacturer.
- Releases tannins and humic acids, which give the water an amber, tea-like tint.
- Can gently reduce KH, which helps keep conditions closer to those preferred by tropical fish.
- Recommended dosing of about one cone per 10 litres of water, with no preparation required.

What it works with
The cones suit tanks with soft water, especially for betta, neon tetras, corydoras and shrimp, which the manufacturer specifically recommends. Because the effect on pH can be stronger in very soft water, regular testing of pH and KH is advised. The water colouration is natural and, according to the manufacturer, safe for fish and shrimp.

Frequently asked questions

The recommended dose is about 1 cone per 10 litres of water. They can be placed directly in the aquarium without any additional preparation.
The cones usually work for about 2 to 4 weeks. Their effect can also slightly lower KH, which may help keep conditions more natural for tropical fish.
The amber colour is a natural effect and the supplier states it is safe for fish and shrimp. The product is especially recommended for tanks with bettas, neon tetras, kiryski and shrimp.
The pack contains 4 g of alder cones, usually about 20 pieces (plus or minus 2). The supplier notes that the count and weight of each cone can vary due to their natural origin, and packs typically contain 20 to 22 pieces.
