Rashes...

[BT05]

The only problem I've ever had was with palythoa. When first setting up my rockwork, I brushed up against a small one that had gone dormant (yes they can go dormant!). No rash, but it left my entire arm numb for a week. I still had control of my arm, but the sensation was really wierd.

So now I wear gloves as it could have been alot worse.

If you are concerned about toxic buildup you should run carbon in your water every now and then or even 24/7. I would guess that it could help explain the "sudden death" of certain corals that are more sensetive to the chemical warfare going on in our tanks.

There is also a silly myth that carbon will remove all trace elements from your water. It's more like a half-truth - Carbon does remove trace elements but ONLY when the ph of the water is at the extremes. (lower than 4 or above 12 I believe). I don't remember the exact numbers but I do remember that it is nowhere near saltwater or freshwater ph levels. So by the time it does start to remove these elements, everything in your would be dead.

I have a couple of pairs of gloves and have had to become more diligent at using them as of late. I get exzema on my hands when exposed to moisture or chemicals, probably due to long term exposure to all kinds of nasty crap in my former occupation as an auto mechanic. I have prescription cream for it that helps, but its better to not irritate my skin in the first place. About the only time I get my hands wet now is when I feed, and then it's just my fingers. All other tank work is done gloves on. Better for me, better for the tank since I don't want the oils and medications from my hands in there. It does reduce dexterity though for some jobs. I also have to wear gloves when using any kind of household chemicals too. Its a major PIA.
