I have had this tank running for 5 years and my levels have been good until not to long ago my calcium started dropping some days up to 60 ppm and then my pH dropped from 8.2 down to 7.4 so I added marine buffer and then my hardness rose to 16.2 I did a 30 gallon water change and got my hardness back down to 9.0 but now I'm reading ammonia .25 is this from my pH drop or my hardness rise does anyone know if it will recover or should I refuse with bacteria
