Welcome to R2R! While the preferred calcium levels are lower, I don't think I've read anything indicating issues with calcium at higher levels in the 500s. High alk can burn some types of corals. I'd go for smaller water changes as you try to bring the alk down, maybe 5% or 10%.

Too much calcium will affect the values and cause stress on your fish and invertebrates. It can also cause your fish to grow more slowly and swim erratically. You will want to keep calcium between 400 and 450 mg/L. If the levels get too high, the calcium can cause the pH to rise to dangerous levels, since most forms of calcium are alkaline.

I would just lower the calcium level down to around 430 with water changes over a period of time or just let it drop down slowly as it’s used up
