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

Super entertaining toy if your dog likes balls and hunting
Color: Aqua
Love this! We got a similar ball for our dog about 6 months ago and she has been obsessed! We have 2 dogs, one hasa zero interest whatsoever in this toy (as expected) and the other will bark at it while its sitting on the charger so she can get it. Dogs, amirite? lol anyway, the issue we had with the previous one was that it was so loud on our wood floors because it was a solid plastic. The Cheerble ball has made a huge difference in sound for us!
The ball itself is very quiet. When it rolls or bounces on something other than the floor you can barely hear it. With the previous ball we had, we couldn't be on the phone or watching a movie, etc if our dog was playing with the ball because it was so dang loud but this solves our problems! Its made of a hard silicone like material (thing a Nerf ball or something) so it remains quiet. The battery lasts as listed and its easy to charge. It took some time to figure out which setting our dog liked the best but after that it was smooth sailing.
My only only negative to this is that the power on/off switch is inside so you have to twist it open to turn it off and on. The ball will naturally get some saliva on it so its kinda gross to put your hands all over it once its been played with and I'd prefer a button on the outside but understand why that isn't possible with this design.
This ball is perfect if your dog is ball obsessed like ours. Shes a pitt/black lab/aussie mix so ball and hunting/chasing lizards are her favorite past times. If your dog prefers ripping toys apart to kill the squeaker (our other dog) or chewing bones, they may not take to this. Ball is life at our house and this ball is at the top of our pups list, there isn't a day that passes that she doesn't start her daily routine of seeking this out and begging us to turn it on. Highly recommend for the right pup!
