Fishless Cycled Stalled, Help!!

Don't use "high PH" test. Just the other PH test. I suspect your PH might have crashed due to the build up of nitrate. If you see your PH is below 7 and dropping, you might want to do at least a 50% water change.

How much ammonia are you adding every day right now? Do you mean your ammonia only drop by 1ppm every day for 7 days straight? If that is the case, I would do the test again to be sure. Make sure you use the test kit correctly. Some tests do require extensive shaking the test tubes.
