Simple method of dosing alk?

[ponokareefer]

So I added Kalk, not alk, through the morning, and my alk shot up to 8.3, and my calcium maintained at 450. I had no idea adding kalk would increase the alk so much, and leave the calcium pretty much the same. Thanks for the helpfull tip.
After sorting through everyone's advise, and my goal being to try to simplify the process of keeping the levels in my tank constant, I'm going to look for a ATO, and have a smaller holding tank(10gallons). Although I'll have to add water regularly(I get about 1.5 gallons of evaporation in the winter, and close to 2.5 gallons of evaporation in the summer), this will still be easier than doing it daily. This will give me the opportunity to add kalk to the system, and keep my salinity at more of a constant.
Thanks for everyone's advise and help
