JBL ProAquaTest pH 7.4-9.0 ＆ リフィル

My African cichlid tank needed constant pH monitoring and this kit is so easy to read, even my kids can match the colors. The refill means I’m not rebuying the whole set every few weeks, which is a huge win.

I’ve tested this against my tap water and the color chart is dead-on accurate, which beats the guesswork of strips I used before. The drop method takes maybe a minute and the readings stay consistent even in my brackish tank.

We keep it right by the tank now — the color chart on the vial makes it easy to match the shade even in dim light, and the refill bottle stretches way further than I expected. It's the first test kit I've used that doesn't feel like a science experiment.
