    • Any size calcium reactor listed can be fabricated to use the LSM sulfur media and the prices are the same as the comparable calcium reactor.
    • Reactors are sized according to chamber size; the first number being the diameter of the tube and the the second set of numbers being the height.
    • Pictured is our NR612 nitrate reactor. The chamber is 6″ in diameter and 12″ tall, the pump used for this model is the Sicce Syncra 1.5
