It is difficult for me to determine its accuracy because there is nothing else to compare it to. Although the readings are inconsistent, they are Observing the phosphate level drop since I turned on my GFO phosphate reactor, I can see that it is gradually decreasing. There is no way to change settings, so I gave it four stars since the tray was very thin. Additionally, I wonder if the liquid reagent might be easier to use than the powder reagent. A year after the previous update, here is a new one. There are 100 packages of powdered reagents included in the tester. Having used up about 50 so far (one a week), I just realized that they're already expired. I have no choice but to throw away the rest of the stock. The star rating was changed to two (it was four before).
