Alkalinity high!

[Dinodanger]

Adding marine buffer has sky rocketed Dkh to near 14!
I was wondering if the Dkh will drop naturally with around 10 lps corals in a 250 litre or won't there demand be high enough to make much difference?

Yeah,
If your corals are in-taking cal and alk, then your alk will drop.

Just don't dose anymore alk products until it hits your sweet spot.

FWIW:
PH buffer is just a cover up product that does raise your alk too.
It also contains borate and that junk can throw off your test kits, over the long haul.

You've most likely have a lot of Co2 trapped in your water.

Alkalinity and Co2 is what determines your ph.

How did you decide how much to dose?

Estimated from the recommendation on the bottle and tested for pH after

If your salt mix is high, change to a brand where the params match closest to what you want them to be
