Is your test kit old? Check experation

What test kit and salt are you using? Very weird that after a water change your alk is that low. Your best bet is to buy esv part A and B the gallon size. Buy a couple of dosers from BRS and start dripping. Forget about manual dosing, it's a pain in the ***, and it's never accurate.

I keep my mag at 1450-1600

Testing with hanna test kits and Red Sea pro salt also have a bubble magus dosing pump 30ml--alk 15ml--cal 30ml---mag

You should be dosing equal amount of cal and alk

If I dose that much cal I'll be in the 600 by the end of the week

What additives are you using for cal/alk/mag?

 

[redseamax130d]

Mag--- tech m
Alk/cal --- two lil fishes c balance two part

Whats your ph like and is the tank near any high co2 sources (like furnace, kitchen, etc?) is skimmer intake fed from outside? Co2 levels in the air will make a big impact on the level of alk you can maintain.

About 15 feet from a window

Each aquarium is different...
Dosing Equal amount of alk and ca not gonna work for everybody.
I like to keep ca under 400 and alk about 8 so I dose only alk everyday and ca mostly from weekly water changes. Sometimes I need to add 50ml of ca.

 

[redseamax130d]

I'm going to try and open all the windows and see if the ph go's up
