I'm hoping someone out there can help me figure out what is going on in my tank.
I have a well established:
125 gallon freshwater aquarium
running CO2 because it's a planted aquarium
I have this white dusty, slightly gritty deposit on everything. I can wipe most of it off my plants. Some of it seems stuck on. It's almost like the calcium/lime deposit you get at the top of the tank only it's everywhere.
Has anyone ever experienced this or know how to remedy it? I think it has something to do with my really hard water but not sure why. I tested water straight from my tap this morning and the GH & KH are identical to the tank water.
