CALCIUM Test Kit
Information at API officaial website:
Calcium Test Kit
Liquid Test Kits
Calcium
is one of the most important elements in a reef aquarium. Reef
invertebrates such as corals, crustaceans, mollusks and even some types
of encrusting algae need calcium to grow and remain healthy. Over time,
calcium levels drop as invertebrates use calcium in aquarium water. This
kit allows you to easily and accurately measure calcium levels and
maintain a healthy reef aquarium.
- Measures calcium levels as low as 20mg/L
- Uses titration method, with easy to see color change for precise measurement.
- For use inreefaquariums
Testing Tips:
The Calcium Test
Kit reads the calcium concentration in milligrams per liter (mg/L)
which is equivalent to parts per million (ppm).
Directions:
- Read thoroughly before testing. Do not allow test solutions to get into aquarium.
- To remove childproof safety cap: With one hand, push red tab left with thumb while unscrewing cap with free hand.
- Rinse a clean test tube with the water being tested.
- Fill the test tube to the line with the water being tested.
- Holding the bottle vertically, add 10 drops of Calcium Test Solution #1 to the test tube, cap and shake for 10 seconds.
- Shake Calcium Test Solution #2 bottle vigorously for 10 seconds.
- Holding the bottle
vertically, add Calcium Test Solution #2, drop by drop to the test
tube until the solution changes from pink to the blue end-point. Each
drop is equivalent to 20 mg/L (ppm) calcium (Ca2+). Cap and shake the
test tube between drops. Be sure to count the drops added.
- A pink color should form after the first drop.
- If a blue color forms after the first drop, the calcium concentration is 20 mg/L (ppm) or below.
- As the end-point
is approached, the color will usually change from pink to purple
before finally changing to blue. After the purple color forms, only one
or two more drops should be required to reach the blue endpoint.
Note: Reef aquariums
should have a calcium (Ca2+) concentration of between 400 to 500 mg/L
(ppm). To save time, rather than adding only one drop at at time,
several drops of Calcium Test Solution #2 may be added simultaneously
at first, then the final drops can be added drop by drop as the
endpoint is approached.
For example, if you
think that the saltwater being tested contains about 400 mg/L (ppm)
calcium, you can add 10 to 15 drops of Calcium Test Solution #2 at
once as indicated in step 5, then cap and shake. If the solution is
pink, continue adding drops, one at a time, until the end point is
reached. If the solution is blue, then too many drops were added and
the test must be repeated, adding fewer drops initially or adding the
drops one at a time.
Corrosive:
- Bottle #1:
- Keep out of reach of children.

continue rinsing.

- If swallowed, contact a physician or call a Poison Control Center immediately.

accident or if you feel unwell, seek medical advice immediately (show
