After adding sea salt and live sand 2 days ago there is a white foam ring along the tank and top of the water with a white grainy substance a float. Is this normal?
Yep.Thats pretty much normal.Your filtration system will take care of that in a day or 2.But you can just wipe whats stuck at the surface off with your hand.
I'm going to be doing this soon and won't have a filter on for a month. Just want to prep the aquarium for when I get the live rock and the fish and filter.
