ASKOLL CALCIUM TEST – Titration Test for Measuring Calcium in Marine Aquariums
ASKOLL CALCIUM TEST is a titration kit designed for accurate measurement of calcium concentration in marine aquariums. Calcium is essential for coral growth, invertebrate shell formation, and calcareous algae development. Stable calcium levels are crucial for maintaining a healthy reef ecosystem.
This test provides precise results through a color change titration reaction and is suitable for reef tanks as well as fish-only marine systems. Ideal for advanced aquarists who want full control over their aquarium’s mineral balance.
Kit contents:
• 1 bottle of Ca 1 reagent (10 ml)
• 1 bottle of Ca 3 reagent (50 ml)
• 1 green container with Ca 2 powder reagent
• 1 test vial
• 1 syringe with tip
• Instruction sheet and conversion chart
Recommended values:
• Reef tanks (corals/algae): 400–450 mg/L
• Fish-only systems: 350–400 mg/L
How to perform the test:
Rinse the test vial with sample water
Fill with 5 ml of aquarium water
Add 5 drops of Ca 1 reagent, shake
Add 1 spoonful of Ca 2 powder, close and shake – the solution will turn red-violet
Draw 1 ml of Ca 3 reagent with the syringe, add slowly until the solution turns blue
Multiply the amount used (in ml) by 500 to determine calcium concentration
Example: 0.80 ml × 500 = 400 mg/L calcium
Why choose ASKOLL CALCIUM TEST:
A professional and accurate calcium test, essential for healthy coral growth and reef balance. Helps monitor depletion from biological uptake and ensures ideal marine conditions for all calcifying organisms.
