Saltwater Alkalinity

This is the simplest of test kits. Testing Alkalinity is a breeze to test for. No reason to change to any other test kit.

Good buy!

Test is simple to use, but not quite as accurate as other tests that I have used. I will probably use this along with other tests kits when I need a more precise reading.

Good Buy

Excellent sensitivity/color change. Goes from blue to yellow in a single drop and you can't beat the price or the ease of use. Beats another more expensive test kit that I was using.

I don't like test kits that change from one color to yellow. But this one is the best Ive seen. Its very noticeable change in color.

Good Kit

My first time using API it worked well and was fairly easy to use. I'm new to reef keeping and need an accurate test to monitor all water parameters. I will definately use their full line of kits.
