Can't find the original post, sorry. That Ph is fine. Most ponders will tell
you that 8.5 is fine (that's what mine is) A high Ph is less conducive to
plant growth, but not so you would notice IMHO. What you want to avoid is
swings in your Ph.

I don't know about 8.5 being normal. Do you use well water? Having said that,
a Ph of 7.4-7.5 is fine. I wouldn't worry at all about it. Mine is 7.4 and
always has been. The fish (koi, goldfish, and an albino channel catsfish) are
thriving. Never been sick. The plant are doing fine as well.
