JBL ProAquaTest pH 3-10 & Refill

I’ve been using this test kit for about a month now and the color chart makes it really easy to match the pH level. The refill is a nice bonus since I test my water frequently.

Dropped this into my freshwater tank and got a clear reading in under a minute, the color chart is dead simple to match even in low light. The refill bottle gives you a ton of tests, so it's a solid deal for regular checking.

I've been using this pH test kit for a few weeks now, and the color chart is much easier to read than my old one. It works well for both my freshwater and saltwater tanks without any fuss, which was a nice surprise.
