sorry about the shotty post yes thier is 5 fish and an eel in the tank right now, 3 of wich just got added and wernt planed on i know its too many but out of 4 tanks its the only one they could go in.
the tank was bought for the reason of a proper qt
so copper is fine i did have a couple inverts(general star,1 hermit and 1 snail) they have all been moved and will never return
as far as the fish in 2-3 weeks they will be moved to either a 150g or a 130g depending what i decide to build first. but im not waiting 2 weeks to move the eel and i couldnt find anything saying not to copper them so i just did it and hopefully i wont regreat it.
i would still like to know if i should keep on the skimmer, and if i should expect a jump in amonia/nitrates from killing off the bacteria if copper even kills bacteria.
