Dual-action chemical filter media keeps pond water clean, clear and fish-safe. Marineland® Diamond Blend® Carbon-Ammonia Neutralizing Blend combines fast-acting Black Diamond® Premium Activated Carbon and super-effective White Diamond® Blend Zeolite for superior pond water quality. Effectively removes dissolved organic waste and odors as well as toxic ammonia and chloramines.
Marineland® Diamond Blend ® Ammonia Neutralizing Zeolite Blend is a great choice for use in new fish ponds or in spring when ponds are opened after winter. Use with a media bag in any pond filter.
Always rinse filter media before use to remove excess dust. Black Diamond crackles and gets warm as it is being rinsed. This is normal, letting you know it's ready to go to work.
