maybe you guys know - PH swing

Well I didn't think that 8.8 was like Mega-high... mine fluctuates and is regularly touching 8.7

But what if it was on the way down?

How long have you been back... I would wait a while for the corals that you still have to acclimate before I started again.

When I had my kalk accident, I did a 50% water change for 2 days in a row. I did another 25% 3 days later. That brought the PH back down. I lost some acros but everything else survived.
