API Freshwater Master Test Kit

I’ve been using this kit for a few weeks, and the high range pH test has been spot-on every time compared to my old strips. It’s a bit more steps than I expected, but the clear readings are worth the extra effort.

The ammonia test turned bright green right out of the box, which confirmed my cycle crash in minutes. I've been checking pH and nitrite weekly since, and the color charts are way easier to read than I expected for the price.

My angelfish were looking stressed, so I ran the full battery of tests. The ammonia and nitrate readings were spot-on, and I finally got my tank balanced in one afternoon. It's way more reliable than those dip strips I used before.
