That would suggest that eco-complete does raise the PH assuming your source water is the same and is effecting yours quite a bit. How buffered is your water? I know dropping the PH of mine is a challenge and more fidding than I want to get into and more added expense.
I think my best bet might be going with a substrate that is inert then that is one less thing to worry about.
Thanks for posting your numbers.
