The pH has been low in our three reefs lately. We have our windows open, have floor fans going day and night, and I dose kalk each night. Tanks are in our living/dining rooms. I've been fiddling with Randy's "baked" baking soda and baking soda recipe a bit lately, and recording proportions for each of my own recipes, so I can dose a bit of the "raise pH recipe" each day to raise pH. Am keeping records of pH before and after adding the mixture.

After two whole days of dosing and monitoring, I'm not noticing a huge change in pH, but I'm not expecting large changes with small daily does anyway. I'd be happy if morning pH rises .5 to 1 over the course of a week. Once I get pH up where I want it, pretty much anywhere between 8.0 and 8.4, I'll adjust the recipe to maintain pH instead of increasing it.

Sorry to hear about your corals

THat is what i had to do If you can vent your skimmer with fresh air you will see a huge difference. That is what I did and my PH went from 7.8 to high 8.1 to low 8.2 So it does work
