The nutrition tablets are perfect for breeding colonies, and provide ample vitamins and minerals for baby shrimp and snails, as well as full grown adults. With two different types of calcium in one jar, you can ensure your crustaceans have a varied, and complete diet.
 
Why do i need them?
Prevents:
calcium deprivation (nearly ALL aquarium inverts are calcium deprived) 
weak, damaged shells
no more failed molts
prevent premature death
The aquarium hobby was meant to be enjoyable for everybody! That means you, and all of your aquatic pets. We have to stop the ongoing care deprivation of our scavenging critters. Dont be the hobbyists who starves their shrimp or snails - they are just as important as your "showcase" fish. Without their optimal health, your entire fish tank ecosystem will feel the effects too.
Encourages:
breeding
healthy youngster growth
strong beautiful shells
healthy, fulfilled ecosystem - just like mother nature intended
Whether you're breeding top quality shrimp and snails, or you're keeping your inverts as part of your community, you definitely want the healthiest bottom dwellers possible. KatsAquatics tablets not only supply them with calcium they want so dearly, but dozens of other essential vitamins and minerals such as : Vitamins A, C, K1, B6, iron, and phosphorous for optimal nutrition.
