This filter media kit is aimed at aquarists who want to limit nitrite, nitrate and phosphate in an aquarium that already has a filter. Each sachet combines a biological and a chemical stage, so it addresses both the bacterial processes and the adsorption of contaminants in one insert.
Why it matters
- The insert combines biological and chemical filtration, which the manufacturer describes as the reason it works both steadily and quickly.
- It is declared to remove NO2, NO3 and PO4, and the supplier states it helps prevent algae growth.
- The activated carbon and organic carbon content are the two components responsible for the chemical and biological stages respectively.
- A used sachet can be regenerated by soaking it in a 10% salt solution, then rinsing out the salt with clean water. The supplier notes that efficiency gradually drops with repeated regeneration.

What it works with
The sachets are placed in the filter (canister, bucket or internal) or in the aquarium at the filter outlet, and they suit tanks where one sachet per 60 l of water is the dosing guideline. Higher flow speeds up the action but also means more frequent regeneration. Rinse each sachet under running water and shake it about 20 times before first use.

Put it in a canister, hang-on-back or internal filter, or place it in the aquarium near the filter outlet. Higher water flow works faster but means the sachet will need to be regenerated more often.
Soak the sachet in 300 ml of a 10% salt solution, shake for about 10 minutes, then leave it to soak for one day. Rinse out the salt with clean water, and the sachet regains its effect. Each repeated regeneration gradually lowers its efficiency.
