Well it's now been 4 days since removing top layer of SB and 5g WC using IO salt mix.
Usually my SB would be completely covered in diatom looking "stuff" by now. As of today just a few tiny areas exist. I am elated to say the least!
So was it the Reef Crystals causing this issue all along? No other explanation. It is the only thing I've changed.
You can't rule it out, because of your experiment.
But keep a eye on your ca. and alk.
