Red Sea Reef Foundation Pro Multi Test Kit (CA, KH, Mg)

The Red Sea Foundation Pro Multi Test Kit measures calcium, alkalinity and magnesium, three parameters used to manage the mineral balance of a reef aquarium. It combines the individual Pro tests in one kit for routine monitoring and supplement planning.

Each parameter uses titration: a measured amount of reagent is added until the specified endpoint is reached. The kit includes glass vials and Red Sea's titrator to help control the addition of reagent. Follow the procedure for the particular test, since sample preparation and result conversion differ between calcium, KH and magnesium.

Record results over time to understand consumption before adjusting supplements. Clean equipment and consistent endpoints matter more than testing quickly. This kit measures water chemistry; it does not automatically correct it, and replacement reagents should match the specific Red Sea Pro test being replenished.
