Fluval Edge

I am looking for some advice on my new nano tank. I have converted a Fluval Edge 6 gallon tank into a saltwater tank. It has been up and running about 3 months now and has fully cycled. It is a fish only tank right now, but I am finishing up the lighting modifications to allow coral growth. Currently I have one percula clown fish, a cleaner shrimp, and a clean-up crew. I plan on adding soft corals shortly, but after testing the water I have some concerns. Below are the current water conditions as recorded during my last water test.
PH- 8.2
Salinity- 1.023
Ammonia- 0ppm
Nitrite- 0ppm
Nitrate-3ppm
Phosphate- .36ppm
Calcium-290ppm
Alkalinity (dKH)- over 14 which is the highest my test kit reads
Magnesium- 1280ppm
I am concerned about the high alkalinity, low calcium, and low magnesium. The only additive I am currently using is seachem PH buffer which I have to use about once a day to keep the PH up. I have not used anything to raise calcium or magnesium. For those of you who are experienced in reef tanks, what do I need to do in order to get ideal water conditions to start adding corals? I have had a fish only tank in the past, but never a reef tank. Thanks!!
