^My daughter has an AC Frog in one of those^ - nice tank-
Well, NH3 is back to ~0ppm but pH is still >7.5 so I've disconnected the air pump for now. If CO2 doesn't move pH overnight, I'll start (very slowly) adding H3PO4. I found another snail this AM (that's 5 now).
I'll have to see if any of my LFSs carry endlers (I can't recall having seen any).
It seems that only one LFS anywhere in the area carries Eheim. I guess I'll have to try to get Santa to shop online...
