I've been struggling with low pH (7.8) since I started the tank. So I did the experiment of running an airstone in tank water outside. It registered at 8.4ish. I take that to mean I have good buffering (no test for that yet). Then I ran the stone for about an hour inside on different water and it was 7.6 ish! No wonder I feel 80 years old! We have no O2
in this place!
So I need to address the O2
level in the house. Can't really open windows this time of year, or winter either, and don't want to do anything radical like pumping in outside air. How about houseplants in the tank room?
How many and what kind would produce good amounts of O2
? Any ideas?
