Dry Rock and long-term bacterial bloom

[jon.smolders]

No its not cyano... its just a white haze in the water column. Yes, I skim 24/7... fairly wet too but it doesn't seem to have an effect on the bacteria. I have two powerheads near the surface giving me good surface agitation. I'm pretty sure its bacterial because of the low pH and alkalinity. I am open to other suggestions however. Bad bucket of salt? I use Reef Crystals and just opened a fresh bucket and have some water mixing for a 30% water change. Maybe the last bucket was bad? Could magnesium or calcium precipitate out into the water and cloud it for months?
