I took a pic of these but I cant seem to attach it . I think its sort of some POD. Its white in nature and are all over the tank but mainly in the sump and overflow area...They dont move from what i can tell and look like little white bags with little blooms of a sort at the top. Let me know what you think. All of my levels are perfect and I have about 75lbs of LR
. Its a 125 with only 4 small fish in there and has been set up since last Nov.
