I'd like to start with copepods in my tank and was wondering if anyone had any really great or really bad experiences with any of the companies that sell pods and phytoplankton. For now, I have no immediate plans to culture pods or plankton myself, but it is a possibility down the road. I do not have, nor plan on getting a mandarin, so I don't need to keep really large amounts of pods in the tank. If there's someone else I haven't mentioned, but you trust their products/services, please throw names out. Thanks.
