since it is in the beginning of the cycle i would not be to worried about it. 1.023 is not high, unless you are thinking of doing a FOWLR and do not want any invertibrates. i keep my reefs at 1.026. depending on what the S.G. of the tank that the LR came out of, this could have killed the pods. i quick change of S.G. could cause the pods to either pop or implode.
i would just keep an eye on the water quality for the next couple of weeks. by this time you should start seeing more pods lurking around.
