I've started to use regular latex ones but read that vinyl ones works just as well.
From what I understand, its not the water itself that is dangerous. Well it is if you have an open wound and its not healed and you stick your hand in the tank.
The greater danger is getting an abrasion or a cut from a piece of Live rock. This immediate puncturing of the skin allows bacteria from the live rock to enter under the skin and leads to infection. I'm sure bacteria in the water will infect just the same but you would have to already have an open wound. And I don't think anyone will knowingly stick an open cut in the tank.
The gloves will help to protect in the case of abrasions.
I'll definitely keep that in mind. Better safe than sorry. I was just thinking I better have my student health ins. just in case, I've seen some pics online about the risks, although rare, of handling zoanthids.
That's rough @reefer4eva, I wouldn't wish that on anyone :/
