High Calcium

[mapes]

Hi all,

I took a reading with my salifert testing kit and my Calcium came in at around 530. My alk is around 8.8-9dKH and salinity is about 1.028 (Both higher than I would like). I recently hooked up an Apex doser that doses 25ml of alk & calc daily (RedSea A & B solutions). Everything I have read online tells me that I should not stop dosing the calcium without stopping the dosing of the alkalinity. Does anyone have any suggestions as to how to mitigate this high calcium? Should i simply just stop the dosing of the calcium?

Additionally, my display is a 72g bowfront, and total water volume with sump is around 95g. I also do a 10g water change weekly with synthetic salt I pick up from my local fish store.

Thank you!
Tom

Cut the dosing back to say 22 ml and watch the alk. Remove 1/2 gallon of tank water and replace with rodi every day until salinity is 1.026.
I wouldn't react to 530 except to adjust your dosing.

Awesome, will do and thank you for the advice!

And welcome to r2r.
Ask the lfs what they use to make the saltwater. Perhaps their mix is high in calcium.

Thank you, and I definitely will. I was thinking about testing the water next time before I do a water change as well.
