Hello everyone\nSo I woke up this morning and checked my tank. The salinity was a little high 1.030, so i figured when i got home I would add some fresh water. Well while I was at work I got a phone call saying my light was in. I went picked up my light and got about 20lb of live rock. \n\nWhen I got home I fixed the salinity and put my rock in. I then got my light up and running, well when i turned it on I noticed that there is a white film covering mostly everything, its really hard to see except on the bottom of the tank glass, and the bottom of the sump. The pumps and such are also covered in this but it is hard to see. I thought it was just undissolved salt so i tried to stir it up with my hand, but it did not budge. the only way to get it off is to scrape it with my fingernail.\n\nI called my LFS and they said no worries, it may just be some mineral deposits due to high alkalinity and that it would be fine. \n\nSo I just want to make sure that everything is going to be ok being that today was my first live rock purchase. \n\nI tested my parameters and they all report good:\nTemp 77.9\nNitrate 0\nNitrite 0\nAmmonia hard to tell but 0 to 25ppm\nPH 8.4\nSG- 1.027\nWith only 20lb of live rock am I even going to notice a cycle? My LFS said they clean the rock really well so you can add it anytime, and might not even see a cycle. I am not sure when I will be adding more rock. \nOnly thing in the tank is salt water some dry rock and some live rock.\n\nThe water has a lot of particles in it but I noticed a lot got stirred up when I put the dry rock in. I turned my protein skimmer back off for the night because I want to see if that helps any. I know that will be an issue I have to tackle later (micro bubbles). But did I do something wrong? I hope the water clears up too :-(..\n\nI love my light tho!
