If you got money to burn, Lamotte. But, for the rest of us, I'm with John. I used to swear by Salifert, but I tried the new Red Sea kits and they are sweet. Nice sturdy plastic boxes, great agitators, syringes, easy to follow directions, and accurate results that I've seen so far.

I know people knock 'em all the time, but API kits are great for daily testing. I use them and then use the more expensive Salifert and Red Sea kits for monthly tests or when the api kits show something weird.
