Is it Reef Advantage Calcium or just Reef Calcium?
The Reef Advantage also includes magnesium and strontium to help balance out the ca
. The Reef Calcium is strictly ca
and your ca
level could be off due to just adding that and not magnesium and strontium.
If you have only done it once you probably havenâ€™t hurt anything assuming you followed the directions. If you have been adding for weeks your ca
could be off the chart and you may need to do a couple of 20% pwc
Most salt brands are low in ca
and often need additional ca
additives if you have corals that require ca
. As everyone mentioned you should never add to your tank unless you know you need the additive through testing though.
