So I had bought this liquid testing kit about 3-4 weeks ago and I have been using it to (obviously) test the water parameters. I have the whole card that shows what the varying colors in the tubes mean and I have a big question. In regards to the ph, high ph, nitrites, and nitrates all of these have varying color but ammonia the testing liquid is completely clear. Any way I'm writing this post to find out if any one else who has the API Freshwater Master Testing Kit if their ammonia TESTING liquid is clear. Thanks!
