Ph is coming up yellowish. Lower than chart.

This is my obvious issue. I understand the kh can be the culprit when dosing.


Any tips on best way to correct this? I have never before had ph below 8.0



Steve at RCE..... What product do you have in stock that works with my current chems?

I wouldn't go messing with your pH yet

When you say KH 100, what do you mean ? 100 mg/l ? 10.0 degrees ?
If it's 100 mg/l, then I'd say Ya, your pH could be low as that comes out at 5.6 degrees
But even that shouldn't allow your pH to be scary low - maybe near 8.0, but not bottoming out

I'd get a second test opinion of your pH, or buy a pH pen/probe

And you may want to allow you and your tank a week or two to settle into the new dosing before you mess with any additional products
