my water is at 9.3 its set by the state and city. they say it keep the metals content down.(i originally had read something about microbes but that was wrong) i think chloramine has some effect on the ph staying high not sure what else besides salts. weird thing is i take straight tap water at 9.3 do nothing to it and the run off is in the 5's. take that same tap water and add vinegar to it so it registers at 6.5 and the run off is in the upper 7's and climbs. water sitting in a jug that has been adjusted will start to climb. water that hasnt will drop to maybe 8.8 -8.9 and stays there. the other thing i have to consider is the only thing i know about this batch is that it comes from northern mexico. may not mean much too most but it does to me because i know the soil there is alkaline sometimes to the point of being toxic. I'm going to try using a more stable buffer and see if i can bring the run off up to maybe upper 6's or so. right now they improved since i stopped filtering and adjusting the ph down but seem like they need a little more. time will tell.
