Hi there.
My alk is currently at 2,5 meq/l it was a lot lower but i raised it ny using buffer.
How can i raise it even higher?

Good old Arm & Hammer baking soda.
dissolve it in a few cups of fresh water and dose in a high flow area or sump.
This calculator tells how much to dose

If you also want to raise pH at the same time, bake the baking soda on a cookie sheet for an hour or so. :)

Is this safe, it seems a litle risky dumping baking soda in the tank....

You don't dump it in the tank. You dissolve it in a few cups of fresh water and pour that slowly in the tank.
And yes it is safe. We all use it. :)

I use Reef Builder by seachem to raise carbonate alk. I like a more balanced buffer. What is the PH in your tank?

How high do you want to raise it ? Shoot for 0.25 meq/ l / day

I want to raise it to 5 meq, my ph is 8,2

Why there is not need to be that high. The highest we recommend is 4 meq / l. You get any higher than that with a pH of 8.2 and Ca++ in the 400's and you will get abiotic precipitation. Your supersaturation parameter index is Ω 6 at those levels.

Is 2 enough?, should i aim for 4 may be?

We like to see it somewhere between 2.5 and 4 meq / l. 3.5 meq /l is a good number :)
