Not a trap... you will be waiting for the test results like a child on Christmas morning. I test every 2 months, not because I have too, but because with the test Triton gives suggestions on improving the water. Take it or leave it. I follow Tritons advice and am rewarded with a nice mixed reef. I would recommend you do two test about a month or two apart. First test to see "where your at" and the second to see the results after you "fixed" any issues that you think is necessary. After that you can go on the Triton Method if you like or move on to something else. True its not a cheap system but its not really a expensive one either. Saving money on salt and RODI water it all kinds of works out in the long run. Triton made my reef a success which I didn't have with 2-part. Money gladly spent...
