Find a productProduct description
This 3-litre active substrate is intended for planted aquariums of 25–35 litres. It suits hobbyists who want to grow demanding plants without installing a pressurised CO2 system. The substrate is designed to support a bacterial population that generates CO2 from organic matter, such as fish waste.
Why it matters
- Plants can be grown without an external CO2 source, including red and foreground species that are typically more demanding.
- Bacteria feed on organic matter, and the CO2 they produce dissolves in the water, so the supply is maintained by the biological process itself.
- Small gas bubbles rising from the substrate indicate that the bacterial activity is working.
- According to the manufacturer, the substrate structure is designed to limit clumping and support root development. Ammonia levels are reported to stabilise about 15 days after setup, provided water changes are carried out regularly.

Frequently asked questions
No. According to the manufacturer, the substrate is designed to support plant growth without CO2 dosing, because bacteria in it produce CO2 themselves. Some plants, including red and foreground species, are said to grow well without added CO2.
The recommended ratio is 1 litre of substrate per 10 litres of water, so a 30-litre tank needs about 3 litres. The pack contains 3 litres, and the suggested aquarium volume is 25–35 litres.
The manufacturer states it is safe for plants, shrimp, fish, snails, amphibians and other aquatic and semi-aquatic organisms. The product information does not describe any specific tests for these animals.
The manufacturer says ammonia levels stabilise after about 15 days, provided water changes are done properly. This is intended to limit algae and support plant growth.
According to the manufacturer, it buffers the water to a range of about 6.4–6.8, which is suitable for most aquarium plants. The same product information states this slightly acidic range can also help plants absorb nutrients.
