I have been curing 50lbs of southdown sand in a rubbermaid for about a week and half, I added some flakes and mixed up the sand twice. I tried to put in a half a cup into my tank and PUFF I had a sand storm so thick I could not see in the tank to pour the rest in. My drip plate over the bio balls seems to have a chalkie like coating and also my skimmer has the same coating in the collection cup. What went wrong, did I try this too early. Can I add more or should I wait? :help:
