Best product for color challenged peopleJan 7, 2018
I was battling green algae in my tank. I was checking everything but someone on Reef2reef suggested I test my water source. My LFS was selling me RODI that for some reason was high in phosphates. It wasnt until I started using the Hanna that I could find a source that was acceptable. I cant wait to get the other Hanna tools.
ULR Phosphate CheckerDec 9, 2017
This checker is probably one of the easiest and most intuitive tests/testers out there for Phosphorous/Phosphates. When setting up a low nutrient tank such as the Triton Method or a Kurallen-Zucht supplement tank, this checker is the best option. Do a simple math equation and you've got your ppm for Phosphates. The test is not only easy, but accurate. For $49, this is one of the cheapest tests/testers per test. I would recommend any of the Hanna checkers for whatever parameter.
