I personally would be more worried about your alk then your cal. As far as bringing them down your corals will eat them up otherwise a water change if your water change water is not that high. RSCP tends to mix with high alk. For some reason I have not had that issue with my last 2 bags but you have to check it.
Alkaline RO water? Test your RO water. If you New water coming in has high alk then it won't help doing a water change. Also if your corals look good and are thriving don't worry about it unless it's a swing. My 75 use to run high alk and did well, my current tank stays at 8.4 with no issues. Every system is different and you can chase numbers all day but at the end of the day, if your fish and corals are happy then leave it be. The cal and alk will drop as your corals use it up if your not dosing. If your dosing scale back your dose, if your using a CalRX then adjust it.
Fortunately high CA isn't too bad of a problem short term. Stop using alkaline water for now and use regular Instant Ocean salt. Your levels will come down naturally. Coral pro salt has really high levels, thats why I only use it when setting up a new reef tank. After that I use what ever the cheapest salt is since I run a CARX and I can keep my levels where I want them.
List of things to upgrade to and are important:
Better test kits. Need to be able to test PO4 (I use a Hanna) NO4 low range, alk, cal and mag (I use Red Sea)
RODI unit or at least a good source of water from a friend or LFS. Personally I don't trust anyone's water but the water I make and I even make mistakes.
Those 2 thing will be a life savers to your tank. I keep 30 gallons of salt mixed and ready to go incase of any issues and I do the same with RODI water. I also check my Alk, Cal, NO3 and PO4 at least once a week and my Mag about once ever 2-4 weeks.
