Hi all! This is my first time posting on your forums. You all seem so nice and helpful. I am fairly new to saltwater (1 year). I have a 60 gallon tall reef tank with a couple of cardinals and 1 clown. I just bought a Seaclone 100 skimmer and I am trying to get it to work properly. Last night I was fiddling with the air valve trying to adjust it and it fell into my tank! I tried my best to find it but after moving rocks no results. Anyone have ideas as to what I can use or if I can buy a new airvalve??? Thanks for your replies!
