Manually dose CA to where you want it. Use the BRS calculator, and advise on how long to dose until desired number.
Keep testing KH, and then restart your dosing based off of the alkalinity in equal parts.

Are you intentionally keeping Alkalinity at 10.4?

10.4 no it?s all out of wack. Will try to do a large water change and see what happens thanks

Let the KH come down naturally and slowly

Test the alk of the new water, some salt mixes have very high alk. This could be the reason why your alk keeps staying so high.

Good luck.

Alk is high and calcium is low.if you do a large water change it might do more harm than good.as Chefjpaul said the safest way is to let it come down naturally,slowly raise your calcium to where you desire it to be then start dosing again.my honest opinion I'm not a big fan of dosing pumps due to them getting clogged or stuck on or off,over dosing..etc..etc.. I went with a calcium reactor and never looked back! Incredible growth and stability
