I'm sure I've read that too Lance .. I just need to be less lazy and look for the info I suppose to be sure because I hate relying on my (apparently flawed) memory.

Anyhow thanks. :) For now the 30g continues to sit in a forgotten corner until the next time I think "Hmmmmmm I wonder if I could use that for ...."

12th question

go for it
 

My experience with hobbyist: we r generally far too paranoid, overly cautious, overbuild, and take extraordinary steps for "precautionary" measures. Taking into consideration what u know about the copper and even IF it is somehow absorbed by the silicone and it somehow is leached back into the water, at what level would it be at? Probably even less than what's in the Trace Elements supplements that we dose into our tanks.

I agree, but I think that is because of (so far) mysterious failures that can kill corals that we have been trying hard/spending lots of money to raise and grow over many years.
I have never used copper or cupramine, but for a 30 gallon tank, it would be worth it to relegate it to some other use. A larger tank, maybe not so much.
Buying a new tank that size is probably on par with purchasing the various copper absorbing materials, test kits and required water changes.

I agree fully with chin lee. Problems do occur that do need our attention but then sometimes just overreact for some simple thing which adds to the already high expense in the hobby "my hermit died now I must do a ton of water change" kinda extreme but that seems to be my view in some issues posted here. I love the hobby but I don't wanna turn it to my second job that i am not getting paid for. For me just keeping it simple and getting a ton of information before jumping into anything would be the best way of keeping all this paranoia and high expense down.

My 110g tank had cupramine in it and I use it now as my mixing tank for water changes. I don't have a lot of inverts but my hermit crabs, nassarus snail and sand sifting starfish are all fine and I've been using it for water changes for a year now. No adverse effects as of yet as far as I can tell.
