Raising alk without PH

[pandaparties]

So I've noticed over time my ph is increasing with dosing for alk (wasser). The past couple months I've seen it go from pH 8.15-8.25 on a given day to 8.3-8.4, alk at 8.0. I'd like to increase my alk but I'm worried about driving my ph too high. Anyone else see this? How to fix?

if accurate that’s perfect, no worries

I guess I'm worried if it keeps creeping up and starts breaking into the 8.4-8.5 or beyond range if I up my wasser to get a higher alk. I get right now it's in a great range but it's trending up even with my current dosing regime

If it gets up to 8.6 consistently, then dose sodium bicarbonate to raise alk and not pH.

It’s probably creeping up because the probe is drifting, calibrate

Nothing wrong with your ph levels. If you want to raise alk without any effect on ph, use TM All-For-Reef.

A word of caution - it will drive your nitrates to 0, if you have a ULNS.

It is likely an inaccurate pH drift. Try recalibrating with new fluid.

I feel pretty comfortable say that no tank has pH too high without dosing high pH additives or having grossly inadequate aeration.

As mentioned above, a bicarbonate alk additive (such as baking soda) will not raise pH.
