Hi all, I am new to this forum & pond management. I have a 1/3 acre farm pond that is over 20yr. old that I am trying to restore. I have recently added a new spring feed to it that will be used to power a waterwheel to aeriate the pond. The spring water has a 8.0 PH & 300 alkilinity. I realize this is somewhat high & am afraid of raising the PH too much. It has a flow of 3 gal. per minute. The pond has a 15ft. depth & is mostly rainfed but also has another underground spring feed of 5-7 gal. per min. that I asume has a similar PH. I just dont want to kill off my fish by adding this spring. Any help here would be apreciated. There is & has been heavy surface coal mining operations in the area for yrs. & most of the springs & creeks all have high alk. & PH.
