Yes the pods in a sump will be sent up to the dt via pump. Chaeto grows best under a certain amount (and spectrum) of light.I see. And you need to also buy a bunch of pods and chaeto (for example) and put in your sump so they can reproduce there? And then will the return pump bring them up into the DT or would you have to swap in new Chaeto for the Chaeto in the pod hotel every so often to replenish the stock in the DT?
Finally, does the Chaeto in the DT require a light on it? Looks like everyone has one
