Strobinol is a natural barley straw-based product with a preventive effect; the pond water remains turbid and clear. The 100% natural effect of barley straw is based on the development of slipper animals and other plankton; the microscopically small animals keep the pond clear for a longer period of time. During the decomposition process of barley straw, useful substances for the pond are released. Strobinol is concentrated barley straw, pressed into user-friendly ‘pellets’. It contains 100% natural organic ingredients and is biodegradable.This pack is sufficient for ponds with a volume of up to 6000 litres.
