Ok, so I search every pet store in town. NO ONE had a Salfert Phosphate Test Kit. In fact the only place that had any kind of a phos test kit for salt water was petsmart and they don't even salt water fish.. Just a small section of products.. Wow. So I got this API kit.. My nitrate chemicals must have been old, because its testing out at 10 ppm. I also did three phosphate tests.
1. Tap Water
2. RO/DI Water
3. Tank Water..
While the tank water changed colors, I can't tell if there is "phosphate" in the tank water. Opinions Please.. Does it look like 0.25 ppm??
