Much better than typical carbon By Dave S. on 9/21/2017Dave S. would recommend this product to a friendRinsed much easier than most carbon and quickly. Even after rinsing could still hear the hissing from the pores releasing water which is much better than the old pelletized carbon. Using this in conjunction with ROWA PhosLock in my BRS 150 and it's working great!
Works well but may not be best for use in reactors By Aaron on 6/22/2016Aaron would recommend this product to a friendI'm using this in a BRS reactor on a recently set up 75g that will be a mixed reef. This carbon does need a considerable amount of rinsing before use (still left a ring of carbon dust around the edge of my sump) but that has been pretty typical of all carbons I've used the past 20 years. Going forward, I would choose something with slightly larger particles for use in the BRS reactors that have larger pores in the sponge that hold the carbon in place.
