Description
Refill for the Red Sea Calcium Pro Test – 75 tests. This pack replaces consumed test reagents in your existing Calcium Pro kit. It is not a complete test kit and is not a calcium supplement for aquarium dosing.
When should you choose the refill?
If you already use Calcium Pro and still have the measuring equipment and instructions, the matching refill lets you continue testing. Check part number R21406 and the test name before buying. Reagents from different tests are not interchangeable.
Getting a reliable calcium reading
Along with alkalinity and magnesium, calcium is an important measurement in a reef aquarium with stony corals. Take repeated readings under comparable conditions before adjusting supplementation. If a result seems unusual, first check sample volume, reagent order and the colour endpoint; one reading should not trigger a large dosing correction.
Follow the instructions for this test and the reagent storage and safety information. Do not return the tested water sample to the aquarium. Keep out of reach of children.
