Dosing PODS?

Ha ok, I thought they were colder water pods because the need to keep the bottle in the fridg.

How do you "overfeed" the refugium with phytoplankton without it all leaking into the main tank? Also I have notice that a lot of my copepods go on the glass when there is a coat of green algae, I guess they eat that too?

The outlet from the refugium to your tank should be near the water line. What this means is that the pods and other live goodies are not flowing immediately into the tank. Some of the pods will make it to the main tank and to avoid them being eaten immediately run an ABS pipe right down to the bottom of your tank. Saw some slits in the pipe near the bottom to decrease the flow further and put rock around it. That way when the pods exit the refugium they find protection and a home to breed in the main tank.
Keep an ordinary light on over the refugium at all times. Overfeed the refugium phytoplankton to keep them healthy and multiplying.
Hope this helps.

What I did is shut off the partially opened valve to the refugium. This allows the phyto to sink down to the bottom and be eaten by all the little inverts including pods. Yes, they love being in the green algae and for that reason the walls of the refugium are left natural
unless the refugium is in the living room and you have a non-reefer spouse/partner.

If you add a centrifuge harvested microalgae to your system you can add large quantities to both your refugium and main tank without any negative affective. Centrifuge harvesting removes all the nitrates and phosphates from the growing media, so you don't run into a problem of adding nutrients and creating an algae bloom in your system. The amounts of nitrates and phosphates in the actual microalgae are negligable.

The more free floating microalgae you add to your system, the more copepods and other zooplankton you will end up with in your system. Its the bottom of the marine food chain, feeding everything else up the chain.
