Tropic Marin

For measuring magnesium and calcium concentrations in seawater.

Magnesium and calcium concentrations and the ratio between these two elements are constantly changing in marine aquariums due to assimilation into the skeletons of corals and coralline algae and the process of precipitation. A periodic check of magnesium and calcium concentrations is necessary to determine the amounts of these elements that needs to be added to the aquarium in order to restore them to natural seawater levels.

The Magnesium-Calcium-Combitest consistently determines the exact concentration of each of these elements separately. Each Magnesium-Calcium-Combitest kit contains reagents for approx. 30 tests.

Hard to read but works

I agree with most people. Hard to read the blue color. Had to run test a few times to get hte hang out of the procedure.

Great Product

This is one of the simplest and most accurate test kits on the market for Ca and Mg. The titration procedure is very simple and straightforward, with definitive end points. I highly recommend!!

Hard to Read, Tedious to Use

Hard to tell when solution is no longer blue compared to the control as the colors never really match. One of the syringes does not have a black O-ring at all so not sure how to read the value for that test and the other has a black one that is the same color as the lines so it's very hard to read the value.

Hard to use

I bought this and found it a bit more difficult to use compared to other test kits. The color change is subtle as well.

Love it!!!

Very simple directions. The color change is subtle but enough to know when it has changed. Use a white background and the change is easy to register. I don't understand the previous complaints. This test kit is great!

HORRIBLE!!!!!!!!!

this test kit is the worst i have ever used. it is so hard to tell if the VERY light blue solution turns colorless that you can only wonder if you are getting an accurate test result. AND, you cannot test the magnesium unless you test the calcium first(you have to use the same solution from the calcium test), and the color change on the magnesium is the same as the calcium. using this is a PAIN!!!!! if they can make the color change A LOT more distinct, this would be an ok test kit, (except for the fact that you have to test the calcium before you can test the magnesium.)

Great

Great test kit. Performed three consecutive tests and all results were within 3ppm for calcium and 5ppm magnesium. Very accurate and reliable.

Blah

The instructions are pretty clear but the color change is very subtle and I have yet to see the MG part of the test work they way the instructions indicate. I've tried it three times over two months (3 on my tank, 1 on newly mixed water).

Really hard to use

The kit has three liquid solutions and one powder. Also, four separate syringes. It's very hard to use - color goes from baby blue to clear and is very hard to distinguish. I still can't get the magnesium test to work at all. Wish I hadn't bought this . . . .
