I ordered the 175 gallon bucket of Red Sea Coral Pro Salt from Dr Fosters and Smith. My delivery arrived today and this is what I found on my doorstep. I have no idea what is in this bucket. There is not a single marking anywhere on the bucket, nothing at all. I called them and they are shipping me out another one free of charge and they sent me a return label so I can return this....So odd since the Red Sea Coral Pro Salt is supposed to be in a black container. Very odd!!
