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

Thank you VIVO
Color: Black, Size: Standard, Color: Black, Size: Standard
Between these cable management trays and the VIVO under desk UPS mount, I have completely tamed the cables at my desk. No more tangling my feet in cables when I stretch. No more messy, unkept appearance. Even with zip ties, I was never able to get anything close to this. It's truly amazing what the right hardware and a little bit of work can do.
Everything you need is in the box. I do recommend drilling pilot holes, even in particle board or softer wood to make it easier to screw in, but the installation is dead simple and done right, no one will even know these trays are there. I should have done this years ago.

Perfect Solution for Desk Cable Clutter!
Color: White, Size: Standard
I’m super happy with the VIVO 2-pack under-desk cable management trays. They’re exactly what I needed to keep my workspace clean and organized. The 17-inch size is perfect for holding power strips, chargers, and all those messy cords that usually clutter up my desk area.
Installation was a breeze — the trays come with all the screws and clear instructions. I mounted them under my desk in just a few minutes, and they feel really sturdy and well-built. The metal construction looks sleek and durable, and it holds everything without any sagging or bending.
Now my cables are off the floor and totally hidden, which not only looks great but also makes cleaning so much easier. If you’re tired of tangled cords and want a neat setup, these trays are a must-have!
Highly recommend!

Perfect cable management
Color: Black, Size: Standard
I set these up on my sit/stand office/gaming desk and trust me when I say I have a lot of cords, power blocks and what not going on. 2 27" monitors (both have DP and HDMI hooked up), two laptops, PS5, gaming speakers, iPad, docking station, phone charging station...and this thing holds all of the cables, blocks AND the Anker multi-plug with 12 outlets. No cords hanging, everything clean. Super easy to install, I totally recommend this product. I like it so much I bought another one for my girlfriend for her home office to get her all set up. You won't regret it
