Definately check out Boomers sujestion cause that can throw you way off and then your even worse off than you were! This is a good named brand teast I use, its called NUTRAFIN calcium test. And if you have an accurate reding on the alk then thats your next step!
Im still wondering how your calcium got away from you cause usually your alk would drop way below the proper ppm in order for cal to jump so high. Was this something that happened overnight or afew days? Was there an over dose of something like Purple UP to make it jump? etc. Are you using a two part solution like ESV? Your alk is rising with your cal so that tells me over dosing to fast. I might be wrong so dont take it to heart. Do a 25% water change and it should drop, then check your parameters after about five hours after your change. Water changes is the quickest way to drop it, do it SLOW tho. Maybe a waterchange every 3 to 5 days until its under control. Your corals will go throug a rough time during this.
I have been through this and I can say it was cause I overdosed with my kalkwasser and alk dripping methods. Slowly change your water and you should be back to normal. Good luck:?::?:
