I think you need to turn off your co2 until you get this figured out....not worth risking fish lives. If you cant figure out your drop checker then you need to do that, I put my glass cleaner (which is gray) right beside the drop checker so it has a whitish background....I also have the double drop checker so I have a reference of what the color is supposed to look like. If you don't trust the chart, don't trust your drop checker, don't have a ph controller, don't know the signs or trust the signs your fish are trying to display, maybe you aren't really ready for injected co2????
