Ok I am in the middle of my fishless cycle. I have ammonia at 2.0 was at 8.0 or greater. Nitrites are at 1.0 and nitrates are at 10 ppm. But my ph was at 8.1 or so now has dropped to 7.8 I have some reef buffer by Seachem do I use it or wait until closer time to add fish after the cycle. I know when I do a water change my ph should go back up after my cycle is complete to remove the NO3 Also should I still have ammonia if nitrites and nitrates are Present in the test. What should I do if anything
