For a few months I've been checking my ph levels religiously. My ph has always ranged around 8.1. I would prefer it to be a little higher to give me some time in case something where to go wrong and I would have plenty of time to catch it. So I started dosing my ph trying to get it a little higher. I would like it to be stable at the 8.3 range. For some reason I dose it and I check it the next day and it still reads 8.1. Today I checked it again an it's 8.0. Why can't I get my ph to raise? Is their something else I should be doing or checking that's effecting it to not raise?
