Did i destroy my tank?

[Notsolostfish]

I usually dose 100ml a day with all for reef hourly 100ml by the end of the day. For 2 days my afr container was empty didnt realize. My alk dropped from 8.5 to 7.3. So what i did was im trying to rise alk slowly. I split the 79ml dose of alk for 3 parts i added 25ml of alk. And then i added the 100ml missing for afr all at once my tank is a 150G loaded with corals how bad did i mess up?

The coral will let you know if they are unhappy. They may be ok if they are generally happy and healthy and unstressed. If they were stressed before the change may cause lots of problems.

Keep going forward steady and slow, gl.
