Have you decided what kind of corals you want to keep?
Salinity seems very low. I'd aim for 1.26 it's the salinity of natural sea water. That should boost your Ca
as well since it's pretty low. Phosphates and nitrates will need to come down a bit more if you want to do LPS
If you really want to do your corals justice, I'd highly reccomend getting a better reef test kit to measure your Alkalinity, Calcium and Magnesium. Red Sea and Salifert make good kits for these.
Also, dosing is not required at the start of keeping corals. Using a good reef salt, dosing doesn't become required until you've got a lot of corals growing in your tank. In my 125 I've got about 15 frags\medium size corals and a clam and still have yet to dose.
