Room CO2 scrubbers

[ToLearn]

I wanted to find out about scrubbing the CO2 not just in the air headed into my skimmer, but in my entire basement. My AC unit runs all day and most of the night, cracking a window can't really be done often enough to make a significant difference this time of year.

I realize this will cost me a little bit, but I want to know exactly how much.

Well my wife's orchids do a great job but that means lights and fans (they like periodic breeze).

If only plant geeks with develop a cross breed of plant that could fit in the corner of a room and really keep up with CO2 creation. May also solve many of the problems destroying our natural coral reefs as well. Then again it may because an invasive species or mutate into some genetic freak that takes over the planet.

I think in the limited space I have plants would be the solution, though I really wish they could be. :-(

You could bring fresh air in with a ERV

ERVs look like a good solution, but a bit expensive and I'm not sure that I could install one on a reanted home and take it with me when I leave.

House plants are the only thing I know of maybe air exchanger, that cools air or heats air as it come in from outside?

Ever hear about carbonate looping? It might be as easy as some air flow like a fan and some racks with CaO which absorbs CO2.

Another method would be bubbling air in a tank filled with caustic. The co2 dissolves in water to produce carbonic acid which is neutralized by the sodium hydroxide. This is a common industrial method as NaOH is pretty cheap and easy to obtain (you pick some 99% in most supermarkets for a few bucks).

Could you explain the second one again? "a tank filled with caustic"? I thought caustic was an adjective. It's like your saying a tank filled with warm or a tank filled with blue. lol Obviously I'm a bit lost in what your saying.

With live plants used as CO2 "scrubbers", don't they have to be really active growers to have any effect? I mean, I don't count on my Bonsai collection to do all that much (grin). Also, what about reverse phase photosynthesis at night? Won't that produce some CO2? I suppose you could light your houseplants at night and your reef during the day...

Sorry, Caustic soda aka Sodium Hydroxide or NaOH. The stuff pretty much was made to react with co2. Just opening the container and letting sit on a shelf will let it absorb co2 from the air.
