You don't have to test daily, just especially if there is a problem, and on a regular basis to make sure what you are dosing is keeping within proper parameters. If a new coral that enters a system RTN's it could be that your other corals are just used to the wrong parameters, but the new one could'nt handle it. Purely conjecture there though. Temp should never vary day to night more than 1 degree. You do have a heater correct?
