I made my own food after reading Doug's thread on the topic, but the oysters I used had too much water in them, so a lot of the food ended up more pureed than planned. But this does mean that there is a lot of tiny stuff floating in the water for my SPS
and filter feeding inverts. I target feed the LPS
once or twice a week with the same fish food mix (cod, shrimp, mysid, clam, oyster, selcon). I just clean my sponge prefilter frequently to keep the uneaten food from spoiling.
