Review on 🐠 Mardel 5-in-1 Test Strips for Freshwater and Saltwater Aquariums by Jessica Romero

These strips are easy to use except for pH testing. There is not much difference between the oranges on the pH comparison chart and the color of the pH strip does not match anything on the bottle. I used a liquid pH test, which seems more accurate (or at least easier to read). Be sure to wait a full minute before testing for nitrates as it takes time for the color to develop.
