Calcium Reactor Effluent

Gtinnel · Nov 25, 2024

After considering it for years I am finally about to start up my first calcium reactor. I have heard that putting the effluent line into a refugium is a good idea so the macroalgae will use up left over CO2 and increase the pH, but I’ve also heard it should be added to a high flow area.

So if I have a refugium with chaeto but it has really low flow would it still be a good idea to put my effluent into my refugium?

Put effluent into the easiest place for your setup.

Both refugium & display would benefit from CO2. Understand this, CO2 is a source of carbon. It combines with water to form alkalinity which when combined with light, produces glucose which is carbon for your reef tank.

Id vote refugium where it may help, regardless of mixing, as opposed to the display where it may hurt.
