Does seachem pristine do the same thing? I have a bottle of that. If not i'll order the Fritz. Did you mean Fritz 900?If you look at the quarantine protocol which is listed as a 'stickie' at the top of the forum, that is the course we usually recommend. With that big a tank - I would have a sponge filter (the large one) - which has a large airstone - or even 2 sponge filters. I would be testing ammonia frequently (daily) with your copper measurements. I would recommend you add a bottled bacteria (for cycling) - such as Fritz 9000, to help with ammonia - it will colonize the sponge filter.
Update: I'm sure they're not the same after reading a bit more, ordering the Fritz 900.
