When your PH spiked to 6, you were then taking out Ca, and Mn both. Keep PH no higher than 5.8 with ALL Macro's and Micro's available. PH imbalance can reveal itself easily in 48 hrs.
Thanks mmman,i bumpped it down last night to 5.8 and when I got up this morning it was back up to 6.0 I bummped back down again,and bumped back down just now.... I bump it down and it goes right back up,I am still a few days off from a newt change,I am thinking I should do it today....
