Unfortunately scallops are exclusive filter feeders and aren't photosynthetic so they don't host the algae that supposedly helps, this is also why they can be so very hard to keep alive, and I agree about adding chemicals, personally I would add more sand a deep sand bed is reconmended to be at least 3" deep and will have anaerobic areas that grow bacteria which can break down nitrates into nitrogen gas although that won't be an immediate fix it may help as a preventitive in the future, and seeing how your tank is relatively young it is possible that this is still just a mini cycle on the way to stability
