How high too high pH

[lilbitreefer]

Looking at getting a co2 scrubber how high should the ph reach before it become dangerous?

8.7 and above was what Randy quoted the other day.

look for 8,3-8.5 as a limit.

Honestly, I’m in so many help threads and there are sooooo many ph posts. I couldn’t find it.
But I’ve been a student of his a long time. 8.5 is the dream ph. At 8.7 you almost begin to see problems.

If you look at this , you can see why.

Also why a 7.5 is almost impossible in a reef tank. As many users report it. (Apex )
Def get two tests.
