Oh, I know as I just purchased the almost $50 for a 6 week supply today from Marine Depot because there are never 6 month reagents anywhere in stock. The $200 a year sell on reagents is slowly slipping away at $50 for a 6 week max supply.
If the 4x a day testing is simple as keeping liquid in the lines and helping the tubes from glazing, etc. Then why couldn't they just make it so if you chose to test 2 times a day then it would actually run an additional two times a day sucking in aquarium water to keep the lines primed, etc.
Please don't take this in any way that I am bashing the Trident. I love my Trident with the controlled dosing with a DOS. One of my best buys to date. However, I wish there was an option or a workaround for those that don't want to test a min of 4x a day.
I do notice you are saying 6 weeks- is your trident throwing errors or getting bad readings before the full 8 weeks? That would worth looking into. I would recommend checking the reagent intake needles (not sure if they would be called tubes or needles; the metal bits ). There are some troubleshooting steps to do, such as cutting the side off of an old reagent bottle and then inserting the lid/needle assembly. It should basically be at the bottom of the container, pointed straight down. That fixes it for the majority of users, some even use a 3d printed needle guide to ensure the tubes stay straight.
Re flushing the lines with aquarium water: it is not just the salt water lines that have the precipitation. The reagent tubes themselves also have the issue, and one could not flush those tubes without contaminating the reagent. Automated testing is a competitive market, especially give the continued sales of reagents. If it was something simple, I really think they would have done it. I know several people who use other devices such as Alkatronic or KH guardian with their Apex units, and now GHL has a device coming up.
