So I am always curious to see what everyone is using to test. One of the things I recently found is the @Aquaforest NO3 Nitrate TestPro Test Kit. I use Salifert and Hannah, as you can see in the below picture, but switched to Aquaforest for Nitrate. The color card is what did it for me. The card is waterproof, and much more durable then what was in the Salifert kit. Anyone else using it? What is everyone else testing with?
