Need frsh O2

[DukeB]

I'm thinking of doing something similar with a fresh air vent (via air tubing) to my skimmer.
I've notice since my windows have been shut more often, that my ph has dropped slightly from summer months. Cracking a window just won't be an option once the 'big freeze' hits.

just my 2 cents, but if you all have furnaces dumping co2 into your houses GET THEM CHECKED!!!!!
A furnace opperating properly will have enough make up air coming into it allowing all the burnt gases to exit through the chimney and not enter your house. If the gases are entering the house you have a make up air problem, which is a potentialy dangerous problem

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.

Thanks Bev, I was mainly curious if it's -just- the pH of tanks or if there were additional "problems" or "phenomenons" that can make one suspect "too much CO2." Short of testing CO2 or O2 saturation of the tank via test kits or along those lines.

Tony,

I noticed no other problems in the tanks, though they were only set up for less than a year. I would suspect older tanks might experience some problems other than low pH, but would not begin to guess what these might be.

The funny thing now, after living with fresh air coming in during the winter, is that I can tell if the condo is stuffy and that the windows need to be open more.

The weather is unseasonably spring-like here lately, so we often open the door to the balcony for awhile a couple of times during the day and evening to exchange the air.

Here is an pic of our old tanks and our dining/living rooms:



Should probably get a new pic, huh?
