Day off so while I was about the house I'm doing a ph profile just to check co2 stability during lighting period and for no real reason other than curiosity I wanted to get a feel for how my 3 tanks vary with regards to GH/KH, while test kits are inaccurate I just wanted a ballpark of this is higher than that and the answers were pretty much as expected, all taken 1 day after a 50% WC on each tank
