Kent salt users

[christyf5]

Thanks Mark. I just heard back from Kent and they do their lab testing at 1.020-1.023 and get Ca = 480, Alk = 9.0 dkH, Mg = 1280ppm.

At 1.026 I've always had Ca = 435, Alk 7.8 and mg = 1300 for like the last 6-7 buckets I've used. I'm just wondering why Ca and Alk are so high.

I ended up buying a second bucket locally (slightly different lot number) and got even higher values than the first bucket (Ca=500, Alk = 15+, Mg=1500+). I'm just wondering if the Ca and Alk have such elevated values, what else in the salt has elevated values? I'm still seeing burned white tips on my sps (those that are already affected are just continuing. I don't see any new colonies affected) but with this second bucket crap as well I can't do any water changes to dilute out whatever got in there in the first place.
