*Welcome to Reef2Reef @megisawesome06 !* You should ask your local aquarium store if they offer free water testing.This will help you take better care of your fish if ammonia is present.Also I use and recommend Omega One Brand pelleted foods for saltwater fish.I have noticed that algae wafers tend to break up in the aquarium and are too large for most fish to eat properly.As for frozen foods mysis and brine shrimp are my favorites.
