Low alk and high calcium?

I have the same problem. My Mag is also on the low side. My Cal is 550 but Mag is 1100 and Alk after dosing everyday for a week of Alk 8.3 is 7.5. The only thing I can think of doing is switch my salt. I was using Tropic Marin Reef Plus. Tonight I will do my first water change with ESV. Mixing kinda sucks but if it is as good as everyone raves it will be worth it. I was going to use Aquavitro Salinity but the nearest place that sells it is 45 minutes away.
What salt are you using?

How much can I adjust it at a time?

add a little baking soda. ALK will rise and calcium drop

that's ridiculous. biodiversity of live rock does dwindle overtime because certain organisms gain superiority and become more dominant. but short of nuking your tank your live rock is not dead. even adding a piece of coral on a small chunk of luive rock adds more diversity back into the tank. I do like to swap out old rock with new rock from time to time to keep all the biodiversity I can but no your live rock is not dead...
also you can easikly keep live coral in a tank that was cycled from pure dead base rock. thee life in your rock has little to do with corals other than as a secondary food source for some.

depends on how big a tank and how much to raise.
using an on line calculator for a 55g tank to raise alk from 6 to 7 dkh requires 6.2 gram, 1.3 tsp, or.2 oz of baking soda.

Yea she said cause it has little Coraline on it it was dead---I just need to adjust my parameters a little
wow, little Coraline = dead rock. that is funny.
if you keep your alk cal and magnesium in balance, as well as keeping phosphates low (phosphates inhibit Coraline growth and can even kill it) you should start to develop nice Coraline growth, as long as there is some Coraline in the tank to begin with.

Person at ***** told me my live rock may be dead? never heard of such a thing? It has been in my tank for 7 years and she said the fish must have sucked everything out of it?
That's the funniest thing I've heard in a long time!

Start by adding 2 teaspoonfuls per gallon of topoff water and measure the result over a week. Adjust up or down depending on results.

So I should be testing for phosphates and magnesium too? I'm already testing ph,ammonia,nitrite,nitrate,alk and calcium?
If you do regular water changes you really don't have to worry much about magnesium, my seachem mag test cost over $40.00...more than a master kit, but absolutly keep a sharp eye out for phosphates and test regularly.
