Marineland Diamond Chemical Filtration Media

Improve pond water quality and clarity with Marineland Diamond Filter Media. These chemical filter medias enhance pond filtration to maintain proper water quality for healthy koi and pond fish.

Black Diamond Activated Carbon
This activated carbon works faster, better, and longer than the rest. Eliminates foul odors, unsightly discoloration, and harmful organic substances. Heat-activated bituminous coal-based granules are specially sized and far more efficient than coconut, wood, or peat-based carbons. Contains less than 2% moisture. Use with a media bag.

White Diamond Ammonia Neutralizer
Removes ammonia to keep fish safe and water sparkling clear. Reduces stress and mortality rate as it protects against ammonia spikes and further toxic buildup. Removes up to 4 times the ammonia of traditional ammonia removers. Use with a media bag.

Diamond Blend
Premium Black Diamond blended with White Diamond makes a perfect combination to rid your pond water of dissolved organic wastes and ammonia. Use with a media bag.

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.
