I have a 4 month system that was started with dry rock and i added a cow scrubber onto my skimmer 2 weeks ago. It bumped my ph to hover between 8.3-8.5.
Then for a variety of reasons I decided to replace all the rock with fresh live rock (aquacultured in the ocean). When I did this, I noticed my ph dropped to 8.1-8.3.
Anyone know why this would happen? I even replaced the cow scrubber media with a fresh bag and same thing. Nothing else has changed in the tank and in my home...
