Hi guys,
I'm panicking. I know it.

Just picked up new fish from the airport (yippee). Brought them home, but my pH was still at 7.2, and they were at 6.8. So I went and bought pH down, put too much in (yes, I know). Now my pH is 6.66 - is it safe to let them out of the bags? Should I use bicarb soda first? They've been in there an awful long time.

Help please?
