Your 75 is filling in quite nicely!Did a water change today on both tanks. I even plugged in my ph probe and tried calibrating it. I checked it against a ph test kit. The apex reads 7.12 and my test kit says 8.2 as usual. I guess I need to break down and buy a new one.
Oh and the hammer coral survived and is doing well. It's a little retracted in the picture because I was messing with it some to get it secure in the rock, but it suffered no lasting damage from my accident last week.
