My house has a gas stove, furnace, and water heater. I have a home CO2 monitor that tracks the CO2 levels in my house. Anytime the Water Heater or Stove is used the CO2 Levels go from around 500/600 to up around 1000 or higher. This always kept my PH changing. I thought about running CO2 media, but ended up running my skimmer air intake outside. Other than the cost of some tubing & PVC to run it outside, it is free.

Am I missing something? Is this not doing the same thing the CO2 Media would (to a lesser degree)? Either way, the overall CO2 is lowered in the tank, because the skimmer is not pulling as much CO2 into the tank, but the surface agitation will still allow the higher home CO2 to work it's way into the tank, right? I think I will always have an issue unless I address my home's CO2 Issue.

Are you confusing Carbon Monoxide (CO, poisonous) for Carbon Dioxide (CO2)? A CO2 detector is rather unorthodox and costly, (but at 1000ppm you'd be sick, so maybe?)a CO detector is common and needed around some natural gas/lp appliances. (I work for a natural gas utility)
But yes, running your skimmer air intake from a line outside would probably eliminate the need for a CO2 scrubber. But in my case, I would have to run a line through my living room 20ft. to pipe in outside air. (Concrete walls and celing, the Misses would not approve )

Any clean combustion of gas (blue flame) should emit mostly CO2>CO I believe. Not only will burning those fuels create additional CO2 in the house but they will also use up available oxygen.

Here's the simplified equation: burning one unit of methane (CH4) uses up 2 oxygen to produce one CO2.

CH4 + 2(O2) ----> CO2 + 2(H2O) + energy/heat

Moving the skimmer intake to outside fresh air is a good idea in general. For many of us it's just not practical.

Yep. (If you starve the appliance for O2, then you get CO instead of CO2)

No, I am not confusing CO and CO2. It is a $90 CO2 Monitor

http://www.co2meter.com/products/co2...uality-monitor

And no you don't get sick from 1000 PPM of CO2
https://www.kane.co.uk/knowledge-cen...d-co2-in-rooms

I run my Skimmer Intake up into the attic, then out through the side of the house. Once I get into the wall, I go up in airline size, then once in the attic, I go up to 1-1/4 in PVC. That way I get good airflow through the long tube.

I've used the airgas and medvet products. The airgas uses smaller granules with more surface area and lasts bit longer. Both are reasonably priced .Both are used in CO2 control in antesthia use for humans and animals respectively.

I never said you can get sick from CO2. I was referring that you would be sick if you had 1,000ppm of CO however.
That is an unorthodox monitor, but a good tool.
Sounds like you have no need for soda lime.

Well, you can get sick, but it takes a lot:

I got curious and found the same CO2 monitor on Amazon for $62. I found I have about 400ppm CO2 with windows open, and about 1200ppm with windows closed after a day. 2 people and a cat... geez. No wonder I have pH issues.

Athmospheric CO2 levels are around 399ppm,IIRC. You probably need to run an airline to the skimmer, use a scrubber and/or dose some calcium hyrdoxide( kalk) in lieu of other alk calcium supplements or stop breathing.

What is the pH at 400ppm room air vs 1200 btw?

Yeah I stated before an airline isn't quite feasible. And I use a scrubber. At 400ish my pH is 8.1 to 8.2 and at 1200 it's about 7.9 to 8.05 when the soda lime is depleated, it's 7.7 to 7.9
Dkh between 9 and 10

Following I'll be using a scrubber soon and looking for good deals on co2. Scrubber media

Been running scrubber with brs media , not much difference,
Gonna change media and monitor
Maybe drill a hole in the wall for air line intake

I have found an interesting phenomenon when a low pressure system is nearing or plowing over like a hurricane or tropical storm, I've found that atmospheric co2 levels go from about 390ppm to 300ppm. Just a south Florida observation I meant to share a while back.

That's quite a change. What kind of device are you using to do the measurements?
