Are you using RO or RO/DI ?
Yup--my bucket of RC has been testing at between 320-340 Ca. That's why I turned to Coralife salt!<a href=showthread.php?s=&postid=11985659#post11985659 target=_blank>Originally posted</a> by tbar
I bought my first bucket of RC two days ago hoping the problem wasn't to widespread. I need to bring calcium up. I just tested it and it is only 340 Ca. Is that the low reading everyone else is getting? I could of bought two buckets of IO for the same price.
