The CaribSea RhyzoMat is an original and natural fiber mat that is ideal for aquariums featuring live plants. Live plants can make a world of difference for the health and aesthetics of home aquariums, but "floaters" can easily ruin even the most carefully-laid planted aquarium plans. To solve this, simply lay a RhyzoMat down at the bottom of your aquarium, then top it with substrate. This natural fiber mat will help anchor plants by their roots as they grow, keeping them solidly in the substrate. Once the plant is rooted, the RhyzoMat aids in establishing a healthy rhizosphere for your plants, creating a complex system where minerals, healthy bacteria, clays, fungal symbionts and more can flourish. This provides all the benefits of organic soil, while staying far easier to handle and manipulate. The RhyzoMat is pH neutral, capable of being used as a biological substrate, and (when left partially exposed) functions as natural cover for freshwater invertebrates. Suitable for use with any sand or gravel, and does not necessarily need to cover the entire bottom of the aquarium - simply place the RhyzoMat where you intend to have plants, and cut or tear to size. Rhyzomat takes the difficulty out of maintaining live aquarium plants, whether you have one or one hundred.
