I added just one 30lb bag to my sps 135g. Took hours for it to clear and I blew off all the corals with a baster. But, I turned on my Tunze and another cloud started up. So I turned it back off.
I wanted to add another bag, but I'm not sure the inhabitants can take another hit like this one. I soaked the sand overnight in ro and rinsed the heck out of it, but it still went nuts in there.
Q: Will this sand ever settle down completely or do I need to lower my flow to almost nothing? I'm using the aragonite oolitic sugar size from Carib Sea.
