Just another dumb question.

I have a 4x7x8 room. Room is sealed white walls. Right now I have a RDWC four site system with only two running with a SF2000 light which maybe too small but just getting a grip on this new build. Will upgrade to two SF4000 or SE5000s. Anyways, I'm using well water and usually well water is high in CO2, and mine is. Burned through my DI resin in 30 minutes. I have used a degasser for my aquarium so I hit the blunt and got to thinking. If I use a degasser in my room, which is sealed, will the oxygenated water suspend the CO2 high enough to get out of the top of the degasser? What if I used a small exhaust fan on the end to pull it out? Just thinking of ideas to not have to deal with an actual bottle of co2 (which I have as I have welding stuff as well)

Can someone please help lol. I'm way over thinking but maybe this could be a great solution for small supplemental CO2. Along with a CO2 bag I might be able to have enough CO2 to grow some cool stuff. Let me know what yall think.

Do you have a lung room or do you control just your sealed room?

Well water isnt high in co2 mate. It is probably high in minerals (actually dissolved in the underground by co2), which is a good thing up to a certain limit.

To supply co2 in a room this size your only option is compressed co2
A bottle will last several month in a sealed room

I'm like 99.9% sure it's saturated in co2, as my well water tests at 25 ppm on any given day. City water tests at 250 ppm and doesn't burn my DI resin up. Unless there is another colorless/non scented gas that will eat up DI resin? I've been using RODI water for ages for my saltwater tank. I mix up 100 gallons of RODI water a month for my tank. I had to use a degas chamber when I used well water back in the day to de-gas the water with oxygenation. It will still burn up prematurely, but not in 40 gallons of RODI water.

your well water measure 25 ppm out the tap ??
if it is the case it is very soft
Why pass it through a RODI filter ?

Also

The amount of CO2 dissolved in water is proportional to the outer pressure. At 20°C, 1 liter water dissolves about 1.7 g CO2 at normal pressure (1 atm). If the pressure is twice as large, the amount of dissolved CO2 is twice as much, 3.4 g.

I wouldn't spend a penny on an exhale bag in a vented room. Plus are you even running enough light to take advantage of a higher Co2 level?

Yes, my well water is 25 PPM. I run it through RODI as reef tanks are very sensitive. We like ti aim for 0PPM water. One ppm is tolerable but will start algae blooms. Thanks foe the information. I will do some more research. My well water pH is 6 most days

I don't think I have a big enough light for co2 to be effective but I will upgrade to 1000 watts soon. Right now we're just getting the ball rolling on this new build.

I meant to quote you on aboves reply. I see you like the blues. I'm a STL native for 25 years. Go cards! Go blues!

Anyways, I don't have a big light yet, but I will. It's not a vented room, it's a hybrid and room exhausts very slowly.
