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

Great, when the can works
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
This is the only sunscreen I buy anymore. Clear, easy to use and no significant smell. Plus air powered spray and biodegradable.
No of which matters, though, when the can won't spray at all or just gives a weak spray that leaves sunscreen in wet spots or no coverage on your arms. Too expensive to not work.

excellent for oily or acne prone skin
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
my skin type is highly reactive to sunscreen and I often have to juggle the desire for sun protection with awful break outs the next day. this is so far the only spray sunblock that's not stupid expensive that hasn't caused acne.
only complaint is that it seems there's not much of the actual product in the can, but that could be due to the fact that I use a lot of it. 10/10

Lightweight, easy to apply, and perfect to use over makeup!
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
This has become my go-to sunscreen, especially for days when I’m in and out of the sun and need quick, reliable coverage. The spray goes on light and even, no thick, sticky feeling or weird white cast. I have sensitive skin and usually react to sunscreens with fragrance or heavy ingredients, but this one has not caused any irritation. I also appreciate that it's fragrance-free and water-resistant, so I can wear it at the beach or on a hike without worrying about reapplying constantly. It feels more like skincare than sunscreen, and I feel confident applying it over my makeup, not worrying that it will make it look cakey or run.

Good SPF spray. Poor spray bottle.
Style: SPF 50, Size: 5 Fl Oz (Pack of 1)
One of the three bottles we got stopped dispensing the spray immediately. The other two were difficult to keep working. The SPF performance was very good. Used in Cabo.
