Now I have no idea on the history of the tank ( copper or not ) the last owner had it set up as a reef. This tank will be my refuguim and I have pulled all of the silicon out and will reseal it - so my question is it the silicon that would hang on to the copper ( if there was any ) - Do you think I would be ok?
yes on both accounts... a copper test kits isnt more than a few dollars/pounds/euros to buy :smile:
any idea how long I should let it set with water in it (so that I can get a reading of read copper or not)? I mean should it have water in for a month before testing it?
