I currently use the AP test kit, but have a dickens of a time trying to tell which one it is if it gets past 20 (which it rarely does), but the colors are so hard to distinguish. All orange/reds and just a variety of intensities of the same colors! Does anyone know of one that is more like the nitrite - blues, lavenders, etc... where the colors are different for the levels and not just various shades of the same color? The ph chart is a good example, it's easy to tell which one. I hope someone can help - I'm so tired of straining my eyes. The ammonia one isn't really easy either. We just go with the top two (it never gets below the second one down - .25) - and say... does it have ANY green in it or not? That's the only way we can get that one either.
Any "easier on the eyes" suggestions would be ever so much appreciated!
