Checked them a few minutes ago and they grew over an inch since last night! Had to tuck their lil heads down under the screen again. Here are their stats:

Red (Left bubbler) = 5.4 PH, 827 PPM
Toots (Right bubbler) = 5.7 PH, 828 PPM.

Adjusted Red to 5.7 PH and left them as is from a PPM perspective.

Did I mention that they grew over an inch since last night? Oh yeah, some pics below...
