Plankton

[Spectre2006]

Whats the easiest way to keep the plankton population up in a 125 reef tank?

Most people just dose plankton as needed. You can use bio-plankton or DT's Plankton (RC sponsor).

If you are really into it, you can culture your own and feed that to your tank.

Also avoid predatory fish that feed predominately on pods. Mandarins, some wrasses, some pseudochromis.
A refugium is also a good way to add plankton to the tank.

I'm talking about larger sized plankton though.

I was thinking of something that replenishes itself on a regular basis. A detrivore or other organism that lays eggs and hatches to free floating stage.

When I feed with oyster eggs, the skimmer pretty much catches the leftovers if left on.

I guess I should look at some of the aquarium water under a microscope and see what I find currently living in my tank.

I've always had peppermint shrimp, and the females always had eggs on them which they release and I'm sure that my corals fed on them.
