Chemical Testing Question

[dymium]

I've got an Aquarium Pharmaceuticals Freshwater Master test kit. I've been using it on my 55 gal. community tank with no problems. However, I've had a brackish tank set up for a while, and I'm wondering if the freshwater kit can be used with the brackish water, or do I need to buy the saltwater kit?

Is there a difference between the specific chemicals used for each parameter, or does the saltwater kit just contain a few extra test parameters?

You may need a SW pH test kit. But the nitrite, nitrate, and ammonia should work fine in SW. If your kit has Kh and/or Gh kits, those will work fine too.
