Calcium High / Need Advise

[kien]

I think your best bet is multiple water changes with a low calcium salt like regular IO. You can either do a few over the course of the week or do larger ones like 50% today, 50% tomorrow and then see where you're at and take it from there.

What do you have in your tank? If things aren't looking stressed out you may be able to ride out the high calc and let it go down "naturally". In other words, there may not necessarily be a need to panic. Yet :-)

I don't have any experience with those salts but that does seem really high if you've done larger water changes with that salt already ? Have you tested the calcium out of a fresh batch of saltwater from those salts to see what the calc is from NSW out of those buckets? Maybe it's an unusually high batch ? In other words, if you test out the calc from newly made saltwater from those buckets and find the calc to be high then ya, doing larger water changes with that salt isn't really going to lower your calc at all! You'll need to find a lower calcium salt.

No, I should have thought of that. Should have checked that first thing. Thanks
