JBL ProAquaTest pH 6.0-7.6 與補充包

The refill pack is perfect for weekly checks—one set lasted me almost two months even with regular testing. I like that the color chart is laminated, so it doesn't get ruined if I splash a drop of water on it.

The liquid tester is much more precise than those paper strips I used before, and the refill bottle gives me many uses for the price. For anyone with a planted tank, this range is exactly what you need to keep things stable.

It was so easy to match the color chart exactly — the liquid drops are clear and the reaction is instant, so I can trust my readings. Makes checking my tank's pH a quick, no-fuss routine.
