Hi All,
Been doing a little planning on our new sump and the more I read, the more confused I get. It seems a lot of people alternate the lighting of the tank and sump to stop carbon dioxide build up and to stop the ph on their tank from dropping. Then they run a calcium reactor and add carbon dioxide to drop the ph and decompose the aragonite sand. Couldn't the same thing be accomplished by letting the tank and sump have a good dark period, which would raise co2 and lower ph, shutting the skimmer of to limit oxygen into the water and running the water through a reactor with aragonite and no additional carbon dioxide?
