Many popular aquatic plants, such as Amazon Swords and Cryptocorynes, have to take nutrients up over their roots. TetraPlant Crypto tablets supply them with all the trace elements they need in a format that they can absorb over their roots. Regular use of Crypto will ensure that these plants remain healthy and grow well. It contains no added nitrate or phosphate, and therefore does not encourage algae to grow.

How it Works
TetraPlant Crypto contains trace elements, such as iron, in a complexed form that ensures they are available to plant roots over a prolonged period of time. It also supports the development of micro-organisms that deliver important nutrients to the plants.

How to Use
Add 1 tablet per 20 litres (4.4 gallons) of water for initial fertilisation. Add 1 tablet per 40 litres (8.8 gallons) for re-fertilisation at each partial water change. Crush the tablets and press into the gravel by plant roots.
