Biotorfin 250ml – plant-based tannins

Biotorfin by Zoolek is a water treatment for fish keepers who want to lower and stabilise pH and keep water clear without relying on synthetic chemistry. It is built on natural plant tannins, so it suits owners who prefer a gentle, plant-derived approach to water conditioning.

Why it matters

• Binds unwanted substances: the tannins precipitate waste protein substances and heavy metal cations that are harmful to fish, transferring them into poorly soluble compounds that settle on the bottom.
• Gentle pH and water hardness control: it slightly acidifies the water and stabilises its pH, which the manufacturer links to better conditions for fish.
• Clearer water and algae control: the product clarifies the water and naturally inhibits algae growth.
• Antimicrobial action: it has antifungal and antibacterial properties, and it also supports plant growth through released humic compounds and trace elements.

What it works with

Biotorfin is intended for fish keeping, where it is used directly in the water to support pH stability and clarity. Its effects on water colour are mild and amber, which is worth considering if you keep clear-water setups. It fits alongside plants, since the manufacturer notes a positive effect on plant growth.
