Hi all,
I have posted on here before about mixing 50/50 ro to tap water. However when I do this my kh is like 1 so I have to buffer it. When I buffer it to 4 it then takes my ph back up to 7.6 and my gh to 12. My standard tap water is ph 7.8 kh4 gh 19. I want to achieve softer water pref around ph 6.8 kg anything around 4 or just over and a gh under 10 as I keep lots of Cory's but I know they like softer water and also wanting to breed them this year so want to achieve a more natural water for them. If I was to use pure ro water how to I re mineralise to achieve the required values above as when I buy to water it comes at a ph of 7 to start with so when re mineralising to achieve kh values by the time I'm done the ph is back up to high 7 and gh back up to about 13. I dont get how people achieve it with ro water.
