Hi everyone,
So, hopefully in the near future I will be getting a whole house R\O system because my tap is at 430 ppm hardness and 85 nitrates. Anyway, the R\O will bring the hardness ppm level down to 0... Basically, my question is can freshwater fish (mollies, guppies, CPD's and Danio Erythromicron after my plants are grown.) thrive at 0 ppm hardness?
Thank you, everyone! :)
 
When you use straight RO water in aquariums you have to reconstitute minerals back into it. Products like Seachem Equilibrium for planted tanks or Seachem Replenish for fish only tanks.

Hi Rivercats,
Thanks for the advice that should work, just wondering though, is there any other options?
Thanks
 
If you go to using all RO water in your tank that is your option... you have to restore some minerals.
