Absolute+ Reptile Bio-Tope Pump 250ml is a concentrated live microbe culture designed to enhance the soil quality in bio-active biotope displays, paludariums, and vivariums. It works by introducing beneficial bacteria into the soil, which are crucial for nutrient recycling, particularly of carbon, nitrogen, phosphorus, and sulphur. These bacteria, minute in size but robust in nature, can thrive under various soil conditions, ensuring the health and productivity of the soil. Ideal for both new and established setups, this culture helps maintain fresh and healthy soil environments. Usage is straightforward: shake well and add 5ml of the culture to one litre of water, then apply to the soil substrate. It is safe to use with foggers, misting, rain systems, or directly in the vivarium, and can be used weekly for optimal results.
