Aqua Medic Denigran Media 4 X50g Bags is a type of granular media made of special plastic material to enhance the settlement of nitrate removing bacteria.

The main nutrient, nitrate is removed from the algae without any chemical additives; additional feeding of the bacteria is not required.

The optimal designed mesh bag gives the best possible water flow past the media.

Depending on the population, Denigran will be effective for up to 12 months.

Content: 4 mesh bags of 50 g each

Application: 1–2 bags per 50 liters of aquarium water

Supports natural nitrate reduction, helps reduce problematic algae

How Denigran helps

Nitrate is produced in most aquaria from livestock feeding and dead plant matter, in larger quantities than it is consumed by the existing plants. One way to reduce the nitrate content is to change the water regularly or to use nitrate filters. In case the tap water has already higher nitrate content and the water desalination or controlling the nitrate filter is too complex, you can use the Aqua Medic Denigran.

It is made from biodegradable plastic that’s uses special bags designed to give low flow rate over the media even in fast flowing water. The lack of oxygen due to the low flow promotes bacteria that remove oxygen from the nitrate. Nitrogen gas then escapes. 1 – 2 bags are used for 50 litres of aquarium water, depending on the animals and nitrate content.
Do not insert all the bags at once, but increase the number slowly at fortnight intervals. It is normal for the aquarium to become cloudy in the initial stage, this is produced by the multiplication of bacteria. If the cloudiness continues then the number of bags can be decreased.

During the time, the granules are reduced by bacteria. The bags should then be gradually replaced, but not opened and refilled. Nitrogen gas accumulating in the bag is harmless. It can be removed by squeezing the bag. Usually, it takes 3 to 6 weeks until the granules are sufficiently populated by bacteria to take effect.
