pH swings affecting corals

I've had good luck with Red Sea Coral Pro. It's pre-buffered, so it keeps things steady during water changes. Just don't overdose it.

If you're dosing kalkwasser, drip it slowly at night. pH naturally dips after lights out, so timing matters. Also, avoid overstocking fish—more bioload means more CO2.

Man, this thread's got more science than my high school chem class. But hey, if it saves my Duncan from looking like a raisin, I'm in.

Another weird thing—my pH stabilized when I switched salt mixes. Some brands buffer better than others. What salt are you using?

True story. I switched to Fritz RPM last year, and my Montis stopped bleaching. Cheap fixes sometimes work.
