First things first, we need to fix the chem in the tank before promoting any dosing. Can't work with anything yet until that's back to par and balanced.

level is 375.
Good news on those numbers. That tells me you simpley need to increase your salinity some for the Mg
to get up to where it needs to be (or at least close to). Let the tank evap down and top off with the new SW
until the main is the same salinity as the 14 gal
you just made. You hopefully won't need the MgCl all things being equal.
Once that's done, it simpley a matter of increasing the Ca
. I think you'll find the tank levels will come up some as well. If you can get the dry Turbo Ca
, you'll be alot better off. Add to your 14 gal
of new water, one round teaspoon of the dry Ca
(20 ml of liq CaCl
) and let it mix an hour or two before using in the tank.
You can either do a series of water changes with that (which I recommend, you'll be further ahead) or you can wait until the salinity is up to the 1.025. In either case you'll need to retest the chem once done to see where things stand.
No amount of kalk
dripping will fix unbalanced numbers like you have. Only once the chemistry of the tank is corrected will you have any success at all. You will also need to be mindful in future to tweek the saltmix for water changes after it's upto the correct salinity. Of which I would urge you to keep towards the 1.025 on the hydrometer or if you get a refractometer, 35 ppt
My lfs doesn't keep Tech-M in stock, but they can order it for me fairly quickly. Also, I can get it in Houston in a day.
I would hold off on that for now and see where we get with the new salinity and a few water changes, there a decent chance you may not need it or at the very least may be able to get away with some epsom salts.
