Red Sea vs API for Calcium

[Jim Tansey]

I often read not to glowing reports about the "accuracy" of API test kits, these are my results over the last couple of months. *= Standard Red Sea Pro kit.

10/5/13 *360/380
10/12/13 *360/350
10/17/13 *330/350
10/21/13 *360/380
10/23/13 *390/420
10/25/13 *420/460
10/27/13 *390/420
10/29/13 *360/360
11/10/13 *380/380
11/22/13 *410/420
11/23/13 *440/420
11/24/13 *450/440

For everyone that craps all over API kits, I have always found them to be very close to kits that are harder to use, and more expensive.
