A few weeks after a muriatic acid dip to my rocks, I was soaking them in hose water. I changedit twice then soaked in ro. Water for a few days. When I took them out they had a bit of a musty smell until they dried. Now that they are in my tank I am getting the same smell, untill I open the lid and let it dissipate. Should I be concerned about the smell? Thank you in advance! Tony.
