Contains essential calcium necessary for the development of coral skeletons and other invertebrates. It is recommended to use this alongside Sera marin COMPONENT 2 and Sera marin COMPONENT 1 Ca - calcium - formulated specifically for seawater. The complete series of Sera marin COMPONENT 1 - 7 is designed for advanced marine aquaristics, providing corals and various lower animals with seven beneficial ingredients that work harmoniously together. Sera marin COMPONENT 1 Ca supplies vital calcium for the formation of skeletons in corals and other lower animals. The optimal calcium concentration in water should range from 400-450 mg per liter. You can easily check the calcium levels using the sera Ca-test. When Sera marin COMPONENT 1 and 2 are combined, they help achieve the ideal pH level found in seawater and maintain the natural balance in your coral aquarium. Dosage: Use the cap as a measuring tool. Always add one capful of Sera marin COMPONENT 1 and 2 for every 100 liters of seawater, allowing a 2 to 3-minute interval between additions. It is important not to raise the calcium level by more than 20 mg/l in a single day.Shipping Notes

Lightweight Balls
Color: A.Orange+Blue+Green
lightweight but solid. Unfortunately, I can't bring to dog park for my dog to play with as the larger dogs will destroy them. Not for dogs that chew through everything.

Too big for puppies
Color: A.Green+Orange
The balls were a bit too big for my 6 month chihuahuas:/ they are as big as a tennis ball so puppies didn’t like nor play with them
