How To Use:
Simply place the block into the aquarium and leave it. The block will then slowly release small particles of food when disturbed by the fish looking for food. If any of the food block is uneaten on your return, carefully remove the remains and discard. Sufficient for 10-15 small fish or up to 6 medium size fish for 14 days. For less fish simply break the block into an appropriate size. Discard any powder produced after cutting.
