My wife loves to use essential oils for many purposes. Mostly for diffusing. She’ll also use for disinfecting, consuming, laundry, the list goes on. There are some chemicals in them that I’m sure are very dangerous for reef tanks. The smell reaches my fish room even. Clove oil contains eugenol which if you’ve ever had on your skin, you’d know it burns you. Anyone have any bad experiences? I can’t say I’ve come across anyone that has. But if I can smell it near the fish, I’m sure some gets in the water.
