Is there any consensus on a recommended type of salt to use or not use? :? I have an old bucket, probably 6+ years old, of Instant Ocean salt that is almost empty and I will need to purchase some new salt in the next week or so. I need it for a 90 gallon reef set up. One thing I noticed with this particular salt was that the Calcium level was only 300 ppm. I have been adding calcium to it to bring it up to around 420 ppm. I read that this was because the typical water supply has about 100 ppm of calcium in it. It was a pain for me, however, since I use RO water.
Thanks in advance for any advice anyone may have.
