Moss perling when initially planted is more likely to be air trapped in the moss, rather than pearling due to releasing oxygen. Similar effect when doing a big water change.
6 days... I think you need to leave longer. You'll get diatoms (a brown dusty algae) appearing for the first few weeks anyway, plus the plants need time to acclimate to being submersed.
