Why doesn't your fridge, your freezer, the heater in your tank only run once a day? Because it is required to run more often to work properly. The Trident is no different. You can choose how many times to test your tank by not buying a Trident, it's as simple as that. The trident has to run 4 times a day based on the reagents and water in the lines in order to work properly and accurately. Don't like it, don't buy one but it's not going to change because you don't want to test that often. It has a minimum number of times to run and a minimum cost per month.
With due respect - the reason that the refrigerator, etc needs to work more than once a day is not to maintain the machine - the reason is that it needs to run more than once a day to perform the function its designed to do (i.e. cool or heat).
The Trident is different - in that - (the poster) doesn't feel he needs to check his alk or whatever 4 times/day but the trident forces him to. Its like you trying to set your refrigerator for 40 degrees and the refrigerator cooling to 33 degrees 'because it has to to work'. Having said that - my only problem was your analogy - not your point - which is that the product is what it is - for the reasons Neptune has stated repeatedly - thats just the way it is

- but its probably a computer thing. I wasn't going to jump right in - but I did want to know when they were in stock.
