top off water...buffer?

[Skeptic9962]

was just wondering what everyone does with topoff water heard alot about people dripping kalk water for there topoff but have to be real carefull with that was wondering if there was just something you are able to add to RODI water so it doesnt throw anything off...

No, you add nothng to the RO/DI water, just the kalk. How much kalk you add to it will detremine what you get. What is your reason for it ?

well what i was actually wondering is if i dont want to do kalk you cant just toss RODI water into the tank for topoff so i usually use ph buffer for the PH and thats it....is there something better then that other then kalk?

 

[Boomer]

Yes you can just "toss" it in You need to add nothing to RO/DI water for top-off. If you want to add a buffer you can. When your water evaporates it takes nothing with it so the buffer is still there to buffer the RO/DI water pH and Alk when added.

guess i was missinformed about that lol was told to buffer it with PH buffer due to the RODI ph being way low...allright that answers my question thanks boomer =)
