Calcium additives?

[molybdenumman]

I have been having trouble keeping my Ca levels up. I have been using Tech CBA/B and the Liquid Reactor with limited success. My alkalinity is fine but I can't seem to get my Ca over 350ppm.

My Mg is fine also, well within recommended parameters.


Can anyone suggest a product to help boost my Ca. I am hoping for suggestions for additives, as my wife will not permit the purchase of a Ca reactor in the near future. Please let me know what has worked for you.

Thanks
