Alright well ive had this problem for almost a month now. I have this white fuzzy gunk stuff filling up my filter stopping the water flow out of the filter. I replaced the filter bio bag thing hoping that would stop it. I got 2 otos hoping they would eat it, they just died after a week or so. Ive asked Christina and shes come up blank. There is hardly any filtration i feel like because of this and there has been a build up for tiny white spots on the glass now.. i just sponged them away last Thrusday, im guessing thats from the lack if filtration.... I donno i just really want to get rid of this gunk! I cant find it any where else in the tank, JUSt in the filter. please help!
