API 603C First Impressions

Arrived with no damage.

But after last night these are a must have for me. It helps get you in the ballpark with your water perimeters. The rest of the test in the kit are much easier to use. A plus is that they don't bleed colors while testing. Nice that so many things are tested with one dip in the water. I will now test my water periodically to make sure everything is ok. Very helpful for checking the water in our tank.

API 603C Final Thoughts

Let me explain.

I wish there were a simpler accurate test for it. It's really accurate and makes me feel like I'm a scientist while doing it. All bottles clearly labeled and tell you how many drops. This is a kit to test for my aquarium water quality. They test pretty accurate when run against my chemical tests. But, I will continue to order Tetra's 6 in 1 until someone makes a better test strip. Not sure if the reading is 0 or more likely something between 0-.
