Barley straw pellets in a drawstring bag
Biological algae control in aquariums & garden ponds
With the DRAK barley straw pellets you can combat filamentous and floating algae in your pond and aquarium in a natural and biological way without using toxins that are harmful to fish and plants.
Among other things, barley straw promotes the development of beneficial microorganisms (such as paramecium), which in turn feed on algae and their spores. In addition, the pellets cause a slight yellow colouration of the water, thus reducing the amount of light in the water and inhibiting algae growth. Both effects work synergistically, i.e. they reinforce each other and thus make life difficult for the algae. Taller plants (aquatic plants) are hardly affected, gain the upper hand over the algae over time and then play their own part in algae prevention by directly consuming algae-promoting nutrients.
DRAK barley straw pellets are pressed from organically grown barley straw using a high-pressure extruder process. Fish and other aquatic organisms are not harmed by the active substances released. On the contrary, the developing microorganisms serve as food for fish fry and, if necessary, fish food such as mosquito larvae and water fleas.
Application
The pellets are supplied ready to use in a drawstring bag made of fine-meshed filter gauze and can therefore be used directly. Please note that the filter bags must never be filled to capacity, as the pellets swell strongly due to water absorption and can otherwise cause the bags to tear. Please place the filled bags directly into the filter chamber or place them in a location with good air flow.
Replace the old pellets with fresh ones every 3 months. The used material can easily be disposed of in the compost or organic waste bin; the mesh bag should be disposed of in the residual waste if it can no longer be used.
Barley straw only works in the long term, but it is sustainable! The algae will not disappear the next day or the day after - you should therefore be patient.
Package contents
3 litres of barley straw pellets in a 5 litre drawstring bag sufficient for 5,000 litres of water
3 litres correspond to approx. 1.8 kg (the weight is not binding as it depends on the residual moisture of the pellets)
For smaller volumes of water, some of the dry pellets can be removed from the net bag and stored dry for later use.

All in all, a good product and good service
Barley straw pellets in a drawstring bag | AMOUNT: 3.0 Litres
I am very satisfied with my purchase of the barley pellets. They have helped to significantly reduce the thread algae in my pond, which had developed due to the change in weather. The checkout process was simple and straightforward, with no delays or issues. I expect to place another order in July, as the effect only lasts for about three months. I have about 20 goldfish of various sizes, and none of them have been affected by the barley pellets. The water does turn a bit brownish, but I hope that the heron (I live near the Rhine) won’t be able to spot the fish because of it. All in all, a good product and good service.

The algae will become less
Barley straw pellets in a drawstring bag | AMOUNT: 3.0 Litres
There is less algae in the fish pond. In any case, you should take the advice seriously: do not fill the bag, the pellets swell.
