my sister has some shells and a piece of coral she got from the beach at galveston tx that i think would look sharp in our fw community tank. i know to wash them thoroughly (actually plan on bleaching them). what i was curious about was will they change my water parameters? the coral piece was an actual live coral at one time and the other shell looks like a small conch shell. if anyone has any experience with these please feel free to chime in! figured you saltwater guys would know about it. i'm mostly concerned about it either taking my ph too far either way and if its okay for my raphael catfish. any thoughts would be appreciated.
