Jeff, I would suggest harvesting your pods on your own. That way you have a constant source. It’s really simple and low maintanence. Just feed them a couple times a week with Brian’s pod food and you can continually add them to your system. Eventually you will have tons climbing thru your macro.
You also have clowns and a wrasse and they love pods too, so I can see why you’re not seeing much in the system. Best time to check is after the lights have been out for a couple hours. Check the rick work with a flashlight. I don’t see many in my 75 because I have a lot of fish that eat them but the 40 is loaded with big adult pods in the DT and running throughout my Caulerpa. Those all started from the little specs in my bucket.
