tomreefer · 07/21/2018, 05:04 PM

I tested my Alk this is results:

Red Sea pro 7.0
Hanna Alk Dkh 6.9

And how do I raise it?

It sat too long. Redsea Salt needs to be used in about thirty minutes

What type of salt are you using?
Have you tested the alk of freshly mixed saltwater?

How often do you perform water changes?
How many corals do you have in the tank?

You can raise alk with baking soda (sodium bicarbonate)
