SUSS8 Posted October 21, 2012 Report Share Posted October 21, 2012 Hey everyone, I have been reading up about RO water as my tap water pH is over 7.0 . So I purchased some RO water from LFS but upon further reading I found that people are suggesting additives to the water because of RO water not having the nutrients fish need? Do I add a additive ? & what kind? Would I be better off mixing 50% RO & 50% tap water? I also have a betta pH buffer powder but the instructions aren't really clear on when and how often I should use it. It just says a certain tbsp treats 20L. Just wondering if anyone can help me clear a few of these questions for me!! Thanks, Muss Link to comment Share on other sites More sharing options...
Rod Posted October 22, 2012 Report Share Posted October 22, 2012 Melbourne tap water is already pretty soft.... 50/50 would work for just about any species.....here in Brisbane it's more like 10% tap 90% RO Personally I don't believe in "buffers".....as such might be relavent for Rift lake cichlids.....but not soft water fish Link to comment Share on other sites More sharing options...
