Review on Seneye Slide Ammonia & pH Testing Kit - 3pk: Ideal range 6.5-9 by Tyra Simpson

Not bad for a ransomware other than it works intermittently. Sometimes at 3am I get a message that my tank is 180 degrees! It's not like this. The reason why the manufacturer claims that you have to buy new slides every 30 days (which sometimes just stop working after 20 days) is due to the calibration of PH, ammonia, etc. Well, there is a "calibration adjustment" in the program . So why buy a "recalibrated slide" when I have to recalibrate it every month when I use a new slide? It would also be nice to have salinity readings, which don't exist.
