Lasts winter was our first in our new, very air-tight apartment condo with in-floor heating. pH in our tanks barely rose above 7.8-7.9, using a pH probe as the measurement tool. Did the farley holmes experiment (before I learned it was his
) and found that pH rose greatly outdoors, but hardly any at all indoors.
Decided to open two windows on opposite sides of the apartment just barely a crack, on the coldest days, to remedy the situation. On warmer days, windows were open more. We have a fan in our den/computer room where temps can get high from the small room/lots of computer stuff. The fan circulated the air throughout the apartment and pH rose in the tanks, and the air in the apartment was noticeably less stuffy. Not only did the tanks' O2 improve, so did the O2 for all the other living things, such as for me and for Chris
One slight drawback is the coolness of the two rooms where the windows are open. But since they're both bedrooms, it doesn't matter a great deal, especially with an extra blanket. At least the people sleeping in the bedrooms have fresh air all night.
