I have only a 3 gallon tank housing fire reds.
I intend to add in crystal reds but my ph is currently in the high 7s almost 8.
I want to add some borneowild humic but I am wondering what is the rate of change?
Lets say I have a ph of 8, humic is supposed to bring down to 6.5 or so, how fast will that drop be? Will it be fatal?
