Curious Discus Tank

[techen]

I was thinking after reading my tap water being such a low TDS at 036 am tempted to look into dicus? Now my water is insanely soft, PH is way down at 6.8 normally lower at 6.6. I mean I have a RO unit but I'd have to buffer the water or can I use pure RO water for discus?
 
Anyway, With the PH and TDS, Is it possible to keep discus in my 450litre/120gallon tank with no issues?

Hi mate you can use 100%  RO water or can do 25% tap water untreated  and rest ro mate. and for 120 and what do u mean Is it possible to keep discus if you meen to breed then ide sey no as fry will get lost in that size if you mean having more then 6 then ye u will be fine just keep ph down and try stay of the buffers for discus mate as you can end up loseing them or making um ill as you oly need be out a bit out on a buffer and u will lose mate.
