Good morning all,

I have a quick (hopefully) question about carbon fixation. I maintain several reef aquariums as my occupation and have recently began to become interested in creating a CO2 scrubber for these tanks. The optimum pH for a reef tank is 8.2, and as the levels of atmospheric CO2 rise in the building, the pH drops. I have seen many CO2 scrubbers built that remove the CO2 from the air that gets pumped into the aquarium; however, I would like to remove the CO2 (or, rather, the carbonic acid) that is already stored in the water. I know CO2 boils off at room temperature, but  my question is, is there a product/method/resin that will remove CO2 from water and be safe for marine life ( therefore not RO/DI methods or anything like that)?

RO/DI

Can you write in full and not abbreviate
Just to make sure no misunderstanding

Reverse osmosis/deionized, perfectly clear in this context.

If you could just aerate with cleaner, lower CO2 air, you can probably reduce the level enough.  Its hard to be more specific, we have no idea what level you need, what level you have generally, what level you have occasionally, and how accurately you can measure.

Thank you -- my brain went blank for a moment

Lots of plants and sunlight?
