I use the high pH test because the regular pH test says it is 7.6. Every morning I would dose my tank to 2ppm of ammonia and 24 hours later the ammonia dropped to 1 ppm so I would dose it again to 2ppm, but now my tank isn't doing that. The last day I dosed my tank with ammonia was Saturday. Saturday morning it was 1ppm so I dosed it to 2 ppm and then at 2pm I added more tetra safe start. Then Sunday morning my ammonia was still 2ppm and I thought it was because the bacteria from the SafeStart needed time. Then on Monday morning it still read 2ppm so I did nothing, Tuesday the same thing and today the same thing. I have not added ammonia since Saturday and my tank still reads 2ppm of ammonia. I just don't know what to do to get it to cycle the ammonia like it had been.
