  • Mazuri® Reef Gel Block is designed to be an essential part of a total feeding system..
  • Feed intake will vary based on age, body size and reproductive status.
  • Prepared Mazuri® Reef Gel Block can be fed at a rate of up to 40% of the animals’ diet to provide optimal nutrition. Never feed dry powder without first combining with water. Water must be of boiling temperature to fully activate gelling agent.
    1. Mix, by weight, 80% boiling water to 20% Mazuri® gel powder.  Adjust mixture to meet desired texture and need.
    2. Mix thoroughly with a spoon, fork or whisk  for one minute, then pour into a shallow pan and allow to cool.
    3. Refrigerate until firm.  Cut into pieces appropriately sized for the animals being fed.
    4. Feed to herbivorous fish.

Caution: Follow label directions: Feeding added selenium at levels in excess of 0.3ppm in the total diet is prohibited.


Storage Conditions
Mazuri® Gel Diets have a 1 year shelf life in the dry powder form when stored in a dry environment. For best results, tightly affix lid on canister after removal of desired dosage or store contents of open bag in container with sealing lid. Store in a cool (75°F or colder), dry (approximately 50% RH) location. The mixed product should be stored under refrigeration for no longer than 7 days or frozen for up to 1 month. It is recommended that frozen batches be individually sealed in amount of usage, as repeated entry into the container exposes gel to oxygen. Once this product is mixed with water to form a gel, it should be handled like raw fish.
