I am confused with my PH. I have literally thrown everything at raising my PH. I have ran a fresh air line to my skimmer, ran an external fuge with an light schedule opposite of my DT lights with a ton of cheato in it, and am dosing kalk at night, with the weather being what it has the past couple of weeks I have the windows open. I still can not break 8.1. Today I have had the exterior door open but the windows closed and this is what my graph looks like. I have no idea why its bouncing like this. My dos is set to turn on at 8.02. For some reason today I can't break 8.02 with out the kalk.
Any insight to what I am doing wrong would be helpful.
