The only difference between the tanks is the one with PH 7.2 has river stones and more intense lighting. They all use aqua soil.
Just interested to see if it is the medicine effecting this or something else.. because it isn't ideal.
Are or have you been performing water changes in the tank with medication(malachite)? I would think that this would have more possibilities than the malachite green of affecting pH readings, especially if tapwater's pH was higher than that of the tank in question and water changes have been more frequent, but I am just guessing. Sorry can't be of more help.
