lets not give the guy bad info. dizcus, it sounds like you never kept discus so please back off on those comments. water changes are the single most important thing you can do for discus. you will never harm them no matter how large the wc. you do not need to buffer your water unless there is something wrong with it. thousands of discus are being raised in tap water. R/O will be needed for breeding wilds, but thats it. don't worry about PH. they will adjust. my wilds are in 7.6 ph and my wc's are from the tap with Prime. I have never treated my fish for anything. they are healthy and are now full grown. go to simplydiscus.com. you will learn all there is to know about discus. discus are NOT hard to keep. all they need is a little extra care and time. more and more people are getting into discus because they are learning that all those myths and half truths about keeping these beautiful fish are wrong. my tank is my first try with discus, and I went with wilds. it's a very low tech tank and easy to maintain. after 15 months I have not lost one fish. my only suggestion would be to purchase larger fish from a breeder or importer. small discus require much more care and time. and don't expect 8" discus. few get to be that size. 6-7" is more the norm.
i breed and sold discus who are you to say:~~>>??? have you even read threw all the post on this thread?i mention where hes getting the tap water from? so your telling me if the breeder or exporter keeped it in controll low ph and you was to put the fish in new condition it will be ok? lolljkasdhflkjsahdflka!!! your funny.
