What salt do you use ? My IO is a bit High ??

[gregzz4]

I understand stability is important, and I realise adding a higher mineral content during water changes is beneficial
But my readings aren't stable, and the salt is adding too much Ca

The IO Salt readings aren't balanced
@ Ca 480 the Alk should be over 14dKH, not 10.5

The Ca is not being used up @ the same rate as the Alk, and it's climbing

June 19
Alk 7.5-8.0
Ca 410

July 7
Alk 7.5
Ca 440-450

I'll keep an eye on it over the next week or two and, if it keeps rising, I'll dose a little Reef Builder ( Alk ) to balance them out

And, ya, I rolled the crap out of the bucket before I opened it
