Yup... adding fresh top off water shouldn't effect your pH at all. If you have low pH, it's most likely not due to your top off water, but for another reason.
Why wouldn't it affect the tank water? I am adding 6.6 ph water to a tank that is suppossed to be 8.2. Without buffering the incoming water, the main tank will eventually start to fall. In my case, it did. My salt water is 8.3 when I mix it. I use Oceanic mix. No problem there. My tank's ph is around 7.6. Everything else is fine. I am still looking for a reason as to why I am battling w/ the hair and cyano
is zero coming from the ro
unit. Tank water is also zero. NO2
are almost undetectable. CA
was 430. MG
was 1410. SG
was 1.025. All of these results were 3 days ago. I am scheduled for a pwc
on Thur. I regularly do a 15 gallon pwc
one a week.
