Seen this CO2 scrubber. Hmm.. if I had a skimmer on my biocube I would be all over it.. couldn't find the link to see what the replacement media would cost.

just found it.. $24.99 for the media cartridges.. that could get pretty pricey on a 1-3 month replacement.

I've been doing some more research on this matter and it looks like you can build a DIY container using some parts from BRS.. Now to just find where to get the media in BULK..

I think this still has some potential.. but it needs to get a LOT cheaper..

Interesting link/product. Too bad the media and unit are so pricey.

I guess piping in outside air or a 24/7 algae vessel are still the least options for mitigating elevated indoor CO2.

The other argument I've found against this is that depending on how much surface agitation you have..In a high CO2 environment, the rate of diffusion across the water might still be too great and would negate the effect.

I'm almost certain this is the case in an experiment I've been conducting. I've ran an air pump sitting on my patio to a biocube skimmer which I've rigged up to basically control salt creep as we all know it sucks as a skimmer. I've noticed maybe a .1 increase overall.. and still not hitting the 8's.. I have quite a bit of surface agitation from an AC70.. so any aeration is counteracted by a larger diffusion of CO2 enriched air. Thwarted again!

looks like snake oil to me, such a small improvment wouldnt make to much of a difference.

step 1. open a window near the tank.

step 2. grow micro algea, it uses co2. as a bounus reverse lite it.

low ph isnt much of a problem as long as your alk and calc levels are proper. also cycling and or unstable tanks will have low ph as co2 buildup is a byproduct of the nitrogen cycle. when you tested the ppm of the co2 in your house what was it? when you tested the ph of the makup water of your last waterchange what was it? did you bubble the water for 12+ hours or did you just throw a powerhead in the bucket and call it good?. by the way to do you a ph testing kit or a meter (like hanna or somthing).

Never tested the ppm in my house, but I know if I'm gone for a week on vacation the pH goes up. Opening a window is not always an option.. FL weather.. 90+ degrees & humid. I mix the new water for about an hour and it registers at 7.9-8.0.. don't see the need to mix water for 24 hours... I mix until it is clear.. registers at the right salinity.. and in it goes. I use a Hanna meter for the readings. I've also done the aeration test outside.. ding 8.3. Low pH isn't a problem for keeping things alive although it does reduce the calcification rate... this can be offset by having a higher alk.. I still think things aren't growing as fast as they could be.

the problem with dumping freshed mixed water is that is starts high and drops after a few hours. airating with a air stone will raise it. i was having problems with low ph for a while and it helped after i did that.

Always airate your salt mix for 24hrs. I have my maxijet mounted to the side of my tub with a hole cut for the air tube to get as much air in the tub that I can. Oxygenation is key to wc water.

Uh... mix until clear.. correct temp.. drain tank... add water... save 23 hours.

No offense, but this post indicates one or two things:

- You have no idea of the implications of elevated indoor CO2.

and/or

- You have no idea what this thread is about.

If a person has elevated CO2 concentrations in their household air, aerating their water indoors generally leads to no change in pH and may well result in a lower pH.

Also, there is little reason to have your water mixed by a powerhead for 24 hrs prior to using it. If you are concerned about equilibrating gas concentrations, use an air diffuser and don't feel a need to use it for more than 2-4 hrs.
