Is there any reason i couldn't use one of the calcium/gfo reactors from bulkreefsupply.com as a 2nd calcium reactor chamber?? I could use a re-fillable di cannister to hold the media - anyone see any downside to this?? thanks.
i would think it would work but not as efficient as most second chambers would hold more media than a ro/di cartridge so that means more surface area to break down the excess Co2.
