Black Diamond Premium Activated Carbon
Premium Activated Carbon eliminates discoloration, odors, and impurities...and keeps on doing it long after other carbons quit. Heat-activated bituminous coal-based BLACK DIAMOND granules are specially sized and far more efficient than inferior coconut, wood or peat-based carbons. And now, new and improved Black Diamond works twice as fast.
White Diamond Ammonia Neutralizing Crystals
Ammonia-Neutralizing Crystals is ideal for all freshwater aquariums and ponds. White Diamond removes up to 4 times more deadly ammonia to keep water clean and fish-safe. It protects against sudden ammonia spikes and helps control the presence of ammonia...especially during the break-in period.
Diamond Blend Premium Carbon Ammonia Neutralizing Blend
Premium Activated Carbon and Ammonia-Neutralizing Crystals is ideal for new aquariums. This special formulation of new faster-acting Black Diamond and super-effective White Diamond cleans and conditions aquarium water, ridding it of dissolved organic waste and odors as it removes toxic ammonia and chloramines. Outperforms other blends by as much as 4 to 1.
