He already said his ph was stable. In his mind, that was his problem... his ph doesn't move off of 8.0 no matter what he does. He's probably going to be like me. My ph is stable at 8.4... I seem to hold that ph all the time... but my alk is high because I use to dose with a buffer on water changes.
I quit dosing, and just let my water changes do the trick. My alk will probably slowly go down as time goes on.
