   Works as intended, but that’s to be expected from red sea which makes excellent precise, high quality products.

   Great product. On another product I ordered the wrong thing and they were very kind to give a partial refund. Love the ease of use of this one.

   Very close test results compared to my Hanna checker. I prefer this Red Sea test to Hanna checker for ease of use with similar test results..

   Pretty reliable Calcium test. Have tried other brands, but I seem to get the most accurate results with RedSea. Recommend to anybody who is serious about keeping their aquarium parameters in check.

   Always use dedicated vials and syringes with these kits. Don’t mix and match between the different tests. I generally consider red sea titration tests very accurate but it really doesn’t matter. Just try to stay with the same tests because it’s more important to maintain stability than to chase numbers.

   This is the only calcium test that is reliable. The other Red Sea test kids are hard to use.
