ELOS Ca Calcium Test Kit

Most corals are primarily made up of calcium carbonate and that is the main reason why it is vital to maintain calcium levels within our tanks to nurture the growth of our reefs.

In this episode of [CVtv] we will be discussing calcium, how to test for it using the ELOS Calcium Water Analysis kit, how to interpret the results and what to do to help you maintain optimal levels.

The ELOS Calcium water analysis kit comes with two different test methods, the approximation test in which each drop equals 50mg/lt and a Precision test, in which each drop equals to 10mg/lt.

Step One

Rinse the test vial in running water, then rinse the vial several times with aquarium water. Once fully rinsed, fill it with 5ml of aquarium water using the included syringe for increased accuracy.

Step Two

Carefully shake each reagent bottle before use. Add 7 drops of reagent A and carefully shake the sample. Add 0.15 ml of reagent B using the black spoon included with the test kit and carefully shake the sample. You may notice some of the powder has not completely dissolved; this is normal and will not affect the test.

Step Three

Add reagent C drop by drop and be sure to keep a running total of the drops administered. Swirl the test vial after each drop in order to mix the liquid thoroughly. Continue to add the drops of reagent C until the solutions changes from a pink/violet color to a blue color.

Step Four

Wait 30 seconds to ensure a stable color change.

Step Five

Multiply the number of drops you have added by 50. One drop equals 50mg/lt. If your test required 9 drops of reagent C to change the solution from pink/violet to blue, then your calcium level is approximately 450mg/lt.

ELOS Ca Calcium Precision Test Kit

If you are looking for a more precise reading, then you will need to perform the precision test. This test will help you determine the calcium level down to 10mg/lt.

Here’s how you perform the high precision test using the data obtained from the approximation test:

Repeat Step One and Step Two of the Approximation Test Kit

Step Three

Take the number of drops it took for reagent C to change from pink/violet to blue color in the approximation test and subtract one. Then add that number of drops to your solution. If your approximation test took 9 drops of reagent C, then add 8 drops to the vial. At this time, the solution should still be a pink/violet color.

Step Four

Add reagent D drop by drop, counting each of the drops. Swirl the test vial after each drop in order to mix the liquid thoroughly. Continue to add the drops of reagent D until you have obtained a change of color from pink-violet to blue.

Step Five

Wait 30 seconds to ensure a stable color change.

Step Six

Multiply the number of drops of reagent C by 50 and then multiple the number of drops of reagent D by 10. Add both results together to obtain a precise reading of your calcium level.

8 drops of reagent C equals 400mg/lt, and 3 drops reagent D equals 30 mg/lt. Add both results together for a total Calcium concentration of 430mg/lt.

Interpreting ELOS Ca Calcium Test Kit Results

If your calcium is low, then you will need to raise it via supplementation. In essence you are adding a form of calcium carbonate solution to your tank to raise overall calcium level.

It is recommended to keep calcium levels in aquaria between 360mg/lt and 450mg/lt.

It is recommended that you raise the calcium level gradually and no more than 50mg/lt a day.

ELOS offers both liquid and powder solution to properly and safely raise and maintain the calcium level in an aquarium to natural sea water levels.

Calibrated droppers to ensure that EVERY drop administered is exactly the same.

ELOS sends random samples of each batch produced to the National Institute of Standard and Technology otherwise known as NIST to validate the test reagents for accuracy and consistency. This ensures that every future ELOS tests are the same accurate test as in the past. No other test kit in the market is NIST certified!
