free tank and sump-taken

[sharuq1]

I had thought about the same thing fishytime, which is why I was going to use it for a freshie breeder project. On the other hand, if it was cleaned really well (all hard water stains out, and maybe even a bleaching too) and the calcium all out of it, then re-filled with water it could be tested for Copper just to make sure there isn't any.

I did this with my 120g as well as with one of my shrimp tanks that had been previously copper treated once upon a time and tested at no copper. The shrimp tank has had shrimp in it and they did not die (good sign). 120g is of course empty but I have my fingers crossed (and toes! ) and it should be fine at Cu=0

I know it sounds crazy but I have used CLR to clean a really nasty tank and it works! I rinsed the you-know-what out of it with water after, then a vinegar rinse, then another water rinse/soak/rinse and the tank has had freshies in it for the last year or so with no noticeable effects. Not sure how I would feel about testing that on salt (I am not that brave), but something to think about anyway.

Yup, you can always rinse the bejebus out of bleach and if you're still concerned put a whack of dechlorinator in there.
