If you understand the life cycle of calamus, you wouldn't worry too much. Yes, cyclops,daphnia etc... can be carriers but with proper quarantine, the cycle is broken.
Also if the pond has no fish in it, there's very little chance of fish parasites because the link in the calamus cycle never existed in the first place.
