Help with alkalinity.

Any thoughts on this...
I have a 20 gallon coral Qt. It has just a sponge filter and rack in it. Has about 15 small coral frags. 1/2 zoanthids 1/2 sps. Lit with mars aqua

My salinity was 1.026, magnesium was 1330, calcium 400, dkh was 7.5

I wanted to boost dkh up so dosed 20 ml 1ml/g)of just the alk part of 2 part which said it would raise dkh by 2. I also dosed 2 quart of kalkwasser as top off thst day. 24 hours later instead of having the expected 9.5 dkh its was 7.6?

Why did it not raise?
