This is my first saltwater aquarium I've had a few freshwater tanks but I'm trying to convert over. I bought some mail order live rock it looked good when it got here went and bought some premixed saltwater from the lfs here in memphis a couple of days before the rock arrived. The rock came in on a Wednesday as soon as fedex left the rock was in my tank, temp was 80 degrees had powerhead, lights, and filter running. On Friday I had some Carib alive Bahamas Oolite "gravel" come in the mail. I drained 2/3rd of the water out to put the sand in without causing a big mess, which didn't help. I've been blowing sand off the rocks like crazy all weekend stirring up the dust over and over again in the tank and have what looks like white hairs all over most the rocks still have some bright colors on the rocks but a whole lot of white hairs. I'll post some pics of before the sand and this afternoon. Any help would be much appreciated. Thank you in advance. And please if you see anything else that looks bad or something that I need to fix please let me know.
