LSM? - is pure granular elemental sulfur, with sulfur reducing bacteria right on it for faster break in. This is the product that is used by many public institutions and is now called for in many split level and dual chamber reactors that are being commercially produced to incorporate sulfur denitrification. When used in conjunction with fine calcium reactor media, such as our original ARM?, this method of filtration makes for a lower nitrate, pH stable environment that is better for your animals.
