Ok so I have been dechlorinating using amquel. I also use an API freshwater master kit to test my water. Prior to using amquel my NH4=0ppm, NO3
=0ppm, ph=6.0. After using it my test results are always (with the exception of a slight mini-cycle when i stocked my tank which is now gone):
=5ppm, and NO2
I have been told that the way some of the liquid reagents test NH4 is by increasing the ph in the test tube to 12-14 and that at that level of alkalinty bonded (but biologically usable) NH4 becomes free NH4 and will give a false test with Nessler's and salicylic reagents based water tests. I have searched the web in an effort to determine exactly what kind of reagents are used in the API kit but I can't seem to locate that info. So I'm wondering does Amquel cause false NH4 readings?
BTW I do a daily 5 gallon water change (37g tank.) I have a good and dirty filter, biowheel, and I only vacuum the gravel when it starts to get really nasty (like maybe once every other month) and even then I will do it in sections so that i never wipe out the bacteria on my substrate all at once.
