You do need to raise your salinity but that will also raise your calcium, since there is calcium in the salt mix. What are you using to maintain your calcium levels?

I don't think it is a big deal having your Ca 485 ppm as long as your alkalinity is O.K. Just don't add any additional Ca until it returns to <450 ppm. The concern with high Ca is it will precipitate on your heater, impellers etc or precipitate lowering your alkalinity. I have had mine drift up to 512 ppm with no ill effects and some try to maintain Ca at 500 ppm to promote coral growth (no proof high Ca actually stimulates coral growth)
