Due to the very high alcohol tax where I live I've found that denatured lab/industrial grade ethanol to be far cheaper than vodka. However, how reef safe are the various denaturing agents present in these ethanol solutions?
I've heard are some denaturing agents are fine, while others are not, does any know if isopropyl alcohol is safe? I'm aware that nopox contains methanol, therefore it should generally be safe, some of these lab solutions are labelled as "5% IPA", I believe IPA is isopropyl alcohol, so if anyone knows if IPA is Reef safe, I'd appreciate it.
