Hanna Instruments HI 758 First Impressions

Thank you.

This is essential for an accurate reading. Some of the readings develop better than others. In my opinion they arent quite as accurate as master test kits either. These strips are not to be trusted as a primary testing method for aquariums. A plus is that they don't bleed colors while testing. It's really accurate and makes me feel like I'm a scientist while doing it. It was also kinda hard to get exactly 5ml Into the tubes.

Hanna Instruments HI 758 Final Thoughts

Using this meter is easy.

So did another water change today and now I have happy fish. The test strips work as advertised. I get a consistent reading every time, retests included. It shows it could be between 1-20 but the liquid shows 0. You mostly find them using API also. Besides these few flaws I have to say it's a great starter kit. I like API products and find them the most accurate.
