I have been having a issue the last month or so with my high alkalinity and now my calcium is high now too.and my ph keeps dropping. I had a bunch of my corals die recently and not sure if it was from this. all I have left are zoas which are doing great, torch that won’t really open and GSP that won’t open anymore. I do 10% water changes every week. What am I doing wrong here?
