Alkalinity still too high

[Corey Shelk]

I posted a whole earlier about my friend’s tank having a massive increase in alkalinity. Turns out it’s because he switched salts and one had a dKH of 8 and the new one had a dKH of 11 and he never adjusted the doser so that seemed to be an easy fix and he completed turned it off. However, a few weeks later and the alkalinity is still extremely high.
Parameters:
Alk ~14.4 dKH
Calcium ~520ppm
Magnesium >1500ppm
Salinity 1.027
Temp 78.2

Can anyone help?

Repeated water changes with a pro salt without knowing consumption will equalize the the tanks parameters to the salts.

Switch back to a lower dkh salt.
Let the params fall naturally.

Yeah he had switched to pro salts and then hasn’t used it since and is going back to get old salt. So you’re saying don’t mess with anything right now and just use the old salt with water changes?

Tell him to turn the doser off.
If he does water changes with a salt that mixes around 7.5 he will be fine while allowing the parameters to stabilize at s lower number.

The doser has been off since their last water change, probably a week or two ago

The tank alk is now higher than the water change water, and still rising?

Yes, although I don’t think it’s still rising. The pro salt mixed to ~11dKH and the old salt mixed to ~8dKH and the tank is ~14.4 dKH

Well, I'd be sure to do water changes with low alkalinity, and you can drop the alk even lower in new salt water before use if you want.

I’ve been trying to get them to do it that way, but he is worried about shocking the system

You can change as small of an amount at once as you want.

Read the technicals on Seachem's Acid Buffer - I have used past few days and my alk is where I want it with no adverse impact that I can detect. Just be sure to manage pH. Or, let corals use over time as suggested by others.
