Biogrunt Long-Life is a base substrate for the bottom layer of planted aquariums. It is placed under a cap of fine gravel or aquarium substrate, and it is intended for keepers who want the bed to keep working biologically for longer, rather than only at the start of the tank's life.
Why it matters
- Nitrogen storage: the substrate acts as the main nitrogen reservoir in the tank, which is the core function of the bed's biological activity.
- Organic matter breakdown: it supports the reduction of organic matter, so plants gain access to a wider range of nutrients as material decomposes.
- Mineral complex: a built-in mineral component is designed to extend the biological activity of the bottom.
- Anaerobic zone prevention: the product counteracts bottom acidification and reduces the formation of oxygen-free zones and accumulation of undecomposed organic compounds.

What it works with
The product is designed for planted aquariums, where it forms the biologically active base under the gravel. Following the layering method, it is set below a separating mesh and a 2–4 mm gravel cap, and the tank is filled and planted before stocking. Fish are added gradually, after the tank has run for a few days.

Yes, it is recommended. Cover the layer with a fine nylon mesh so it does not mix with the gravel, then add 2–4 mm quartz gravel or aquarium substrate on top.
It stores nitrogen, supports the breakdown of organic matter, and helps slow bottom acidification. It also helps prevent anaerobic zones and the buildup of undecomposed organic compounds in the substrate.
Fill the tank with water, start the filter, light and CO2, and wait a few days before adding the first inhabitants. Watch their behaviour and condition, and add further species gradually if there are no problems.
One pack costs 84.99 zł gross. It is sold as a 6.2 l substrate with a weight of 4.2 kg.
