I recently purchased a Coral Life RO
unit. After two weeks I noticed by PH was starting to drop. So I performed another water change. After testing the water I noticed a lower PH. After hours of questioning my life I tested the RO
water before adding salt an noticed it was at about 6.1. I called my lfs
that I purchased it from and they told me it was quite normal for that to happen(you think he would have told me prior to buying it, I blame myself too for lack of research) I used "kent" buffer in my aquarium tank and it brought it back to normal. My question is do I have to do this every time now or is there an easier way. The guy at lfs
told me to add buffer to the RO
water as I'm adding salt to it. What do you guys/gals do??
