Keeping Discus Fish and RO water?

I have heard that it is unnecessary to keep commercially available "farm bred" Discus in RO (Reverse Osmosis) Water, is this true?

Hiya

It depends on your local water parameters. If you have naturally hard water it is essential. Some captive bred discus are more tollerable of slightly harder water conditions, but not by a lot. Aswell as this, captive bred discus aren`t nearly as elegant as wild discus!

If your water is naturally hard you will not have success keeping discus without an RO unit.

Discus specialist forums can give you a bit more advice as I am limited to what I have learnt and do not have first hand experience keeping discus at home.

Good luck

Since discus fish originated from the Amazon river which the water contains very few minerals. The tap water coming from the faucets in most homes contains too many dissolved minerals for the fish.

Many fish from the Amazon River basin do better and are much more likely to breed in aquariums with water that is a mixture of tap water and water that has passed through a Reverse Osmosis (R/O) filter. Why an R/O filter? Because an R/O filter is the most economical way to remove almost all of the minerals from tap water.

So it's up to you

Well.. the necessity or not thereof of offering commercially "farm bred" Discus to RO water is one of current debate involving senior specialists from all over Barnsley (UK) and as far as i understand it, the current conensus is that the truth remains open to sceptical analysis and although some say yes, some also say no. i wouldn't say either, i would say i don't know.

i was told discus are a very hard and delictae fish to keep when i first learnt about them but i was given one several months ago and he has defied all discus discussions he currently lives in a community tropical tank with angels, bristlenose cats, molly's, glo-lights, congo tetras, black widow tetras and a ghost knife along with your common neons etc, i do nothing special to my water except make it warm when i do water changes and use prime water conditioner other than that he gets treated like any other fish and he is thriving, also we keep about 15 of them in 3 bays at work and they get one water change once a week and a ph of 7.0 to 7.6 and we have never lost one

Tengo mucha confianza en los productos de sitios web así que he confiado en comprar un par de aletas de buceo tanta para mí como para mi marido y no me he equivocad, por un muy buen precio he conseguido lo mejor del mercado, las aletas son muy fáciles de poner y se adapta perfectamente al pie y son también, muy buenas para bucear en cualquier agua y mas lo he podido comprar en dos números diferente el mismo producto de calidad, he pasado unos vacaciones muy interesantes con ellas.
