I have several of both and find both to be very good. The fluval IMO gives better filtration while the CF1200 is cheaper. I would rate both of them 8/10.
I do a 25% weekly water change (straight from the tap) on all my tanks without any probs and within 24 hours my Discus usually spawn ( and eat :evil: ) also never had any probs with any of my other fish.
I would like to apologise to all FNZAS members and to Charlie for the indiscretion I made when making known the address he gave me to send the fish which he won in the " tank auction " and hopefully all the adverse comments will be put into perspective and sorted by the admin team. SORRY.
If you have a female which is coloured like a male then it is quite unusual and most probably very sort after. If it truly looks like a male then I suggest you breed as many females as possible because IMO they will be very lucrative.
