calcium additives?

[scrapman]

I used to drip kalkwasser in my 90 gal (20 gal + 20 gal sump and refugium)
Too much fuss.... I switched to 2 caps of Purple Up every two weeks.....
I don't dose...... the system has been stable on autopilot for 15 years.....
Can someone recommend a Calcium additive better that Purple Up?

Thanks

BRS two part...

Test before dosing. Keeping calcium and alkalinity high and stable is important in reef systems.
