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

SO durable & my Blue Heeler LOVES it!
Color: Purple, Color: Purple
My Blue Heeler tears up almost all of her toys if they’re not rubber. This ball is SO durable and she loves it so much!! We’ve had it for 5 months now. She chews on it every day for long periods of time and it’s showing pretty much no wear and tear. I keep wondering if I’ll ever have to pull out the second one from the box lol. It can be hard to squeak with one hand, but it’s easy enough with 2 hands or if you step on it with your foot. It’s hilarious that every time I squeak it she licks her lips. My girl never actually squeaks it while she’s chewing on it, which is actually a plus cuz it doesn’t get annoying when she’s chewing on it for long periods of time. I also love that the ball helps clean her teeth because of the spikes and the size is larger so it’s easy to take it from her while playing fetch. Overall a fun, durable dog toy!
