Red Sea Reef Foundation Pro Test Kit

Caring for a reef tank means caring about the water your corals live in, and the Red Sea Reef Foundation Pro Test Kit puts that control in your hands. This single multi-test kit measures the three Foundation Elements together so you can dose with confidence. If you want to take the guesswork out of your reef chemistry, this is a tool built for exactly that.

What this Reef Foundation Pro kit brings to your reef:

• Tests three Foundation Elements in one kit, Calcium, KH/Alkalinity, and Magnesium, which Red Sea calls the foundation elements for coral health and vitality.
• Red Sea describes it as a high-accuracy titration kit with a stated tolerance of +/- 2.5 ppm, so your readings are precise enough to act on.
• Includes a professional Titrator, giving you the same titration approach the brand designed the kit around.
• Provides 75 Calcium tests, so you can track this key element consistently over time.
• Provides 75 KH/Alkalinity tests, matching your calcium checks for a balanced picture of your water.
• Provides 60 Magnesium tests, rounding out the trio of elements the brand highlights.
• Red Sea positions the kit to enable accurate dosing of Ca, KH, and Mg, helping you adjust supplements with intention.
• One kit handles all three measurements, keeping your testing routine in a single place.
• Built for the reef keeper who wants repeatable, methodical results rather than rough estimates.
• Supports the ongoing maintenance that goes into keeping a thriving saltwater reef.
