All Seas Marine SI021 First Impressions
25 from 0.
The API Test Strips are a good water monitoring system for small tanks. It is easy to use and accurate enough. 6 and run a high pH you will see it could actually be 7. So I got these to try and I love them. This is essential for an accurate reading. They showed the same results as these for the sites they had in common. I tested the water and the nitrates and the ph were pretty high still.

All Seas Marine SI021 Final Thoughts
Great value, Speedy ship!
The key is that you are looking for changes. Tetra has always done that and I will continue to use their products. I found running all the tests took me around 10 minutes. First few strips I used gave an accurate ready. The stripa are easy to use, clear instructions and I gor results in seconds. Not sure if the reading is 0 or more likely something between 0-. In my opinion they arent quite as accurate as master test kits either.
