I set up a 50gallon tank 4 days ago, and just put the live rock in yesterday. I need a little help. First i need these identified. I think they are Aiptasia, but just want to make sure. Also There are a bunch of tiny bubbles on my glass. If i get them they will re-appear after a couple hours. Is this just the cycling of the tank? And lastly, the skimmer that came with the setup does not seem to be working properly. the foam only is about a quarter inch tall and is no where close to going up the neck in the cup. its been running for about 24 hours. Does it need time? the guy i bought the tank from said it worked great. it has a rio pump. thanks!
