Red Sea’s Foundation Elements – It’s all in the balance.

A successful coral reef aquarium is dependent upon maintaining the appropriate water parameters that, in turn, provide the stable environment required by the corals.

Although all the elements found in natural seawater have an important role in providing the optimal water parameters, a few of them have a more significant role in the overall stability. These elements are the foundation of the reef environment and they include the three major elements: calcium (Ca), magnesium (Mg) and bicarbonates (HCO3).

These three reef foundation elements have a major effect on the water chemistry (pH stability, alkalinity and seawater ionic strength) and on many of the coral’s biological processes (skeleton formation, ions exchange and photosynthesis).

Red Sea’s Foundation Elements provides a complete solution for maintaining and replenishing the foundation building blocks of the reef aquarium by providing complete and balanced supplements, formulated to work together for long term use and without changing the ionic balance of the water.

Foundation A

Calcium, Strontium and Barium complex for balanced formation of Coral Skeleton. 

Calcium, Magnesium, Strontium and Carbonate are the basic foundation elements of coral skeletons. All of these elements need to be available in balanced proportions for coral health and growth. Foundation Calcium+ contains blended salts of calcium, strontium & barium in the ratio required by corals and is part of Red Sea's complete Reef Care program.

Ridiculously satisfying!
Size: iPad A16 11th/10th, Size: iPad A16 11th/10th
YES! I am completely obsessed with the SPARIN Screen Protector for iPad! From the moment I applied it, my screen looked crystal clear and felt silky smooth like butter under my fingers. The fit is absolutely perfect for both my 11th and 10th generation iPads, hugging every edge without a single bubble or misalignment. I love how responsive it is... swipes, taps, and even intense drawing sessions feel flawless, like my iPad is brand new again. The protector is tough and scratch-resistant, so I can toss it in my bag without worrying about keys or pens ruining my screen. I also love that it doesn’t mess with the display brightness or clarity, so everything still looks vibrant and sharp. Applying it was super easy and stress-free, which honestly surprised me because I expected a million bubbles or frustration. Five stars all the way for a screen protector that makes my iPad feel safe, sleek, and ridiculously satisfying to use every single day!

Happy With The Quality of This Screen Protector
Size: iPad Air 13'' M4/M3 /M2 & iPad Pro 13'', Size: iPad Air 13'' M4/M3 /M2 & iPad Pro 13''
This is my Amazon review for the SPARIN Screen Protector for iPad Air 13 Inch M4 2026 & M3 2025 & M2 2024 (8th/7th/6th Generation) & iPad Pro 13 Inch M5/M4 (8th/7th Gen), Case Friendly, 2 Pack Tempered Glass, Support Apple Pencil. This is an easy to apply screen saver with few bubbles to smooth out. It is very clear and covers the screen perfectly. I literally can only see it is on because of the cut-out over the camera. It is very thin and transparent. My iPad also responds precisely the same to my touch and pencil, so the touch sensitivity feels great. I am very happy with the quality of this screen protector so far. It seems to be a good quality screen protector. Thanks, Amazon.

Great quality product
Size: iPad A16 11th/10th
This is a great quality product that is easy to apply. It's scratch proof with no glare on the screen. We were able to apply this screen protector with no bubbles on the screen. It's heavy duty and will prevent screen cracking if this is dropped. I would definately recommend this product!

Screen protector
Size: iPad Air 11" M4/ M3/M2, Size: iPad Air 11" M4/ M3/M2
I’m really happy with this screen protector for my iPad. The quality feels really good, and it fits perfectly on the screen without affecting the display quality or touch sensitivity. I was worried it might make the screen look dull or reduce responsiveness with the Apple Pencil, but everything still works super smoothly. It also helps reduce fingerprints and keeps my screen protected from scratches, which gives me peace of mind while carrying it around daily.
