If changing your flow through the sulphur chamber I would actually go the other way and lower it. This will create a bigger O2-Free zone and therefore more anerobic bacteria. If your flow is too high I would suspect that you would get into the middle of the denitrification cycle and not have enough anerobic bacteria to finish the cycle off. (which would seem to be what your test results are showing)
