A few weeks ago I posted a question on here about what this white stuff could be collecting and growing in my filter. Someone told me it was fungus and wouldn't harm my fish. I wanted to get rid of it anyways but have found nothing that will do the trick. Recently I came home to two of my seemly perfectly healthy fish dead. Posted via Mobile Device
Wat causes those toxins? And I have no driftwood in the tank. I've tried primafix and maroxy but neither has worked to get rid of it. Could it be something other then a fungus? Posted via Mobile Device
I agree with redchigh you need to test your water and go from there could you post a picture of what you say is fungus? Also how long has your tank been set up, what size is it, and what fish do you have in it.
I haven't been able to test the water yet because I'm out of town. I can try to post a picture when I get back but that failed in my last thread because it doesn't show up well in pictures. My tank has been set up for about 8 months. Its 10 gallons and has 1 molly in it now. there were 3 mollies but two of them died as I said before. Posted via Mobile Device
Molly are very highly sensitive to ammonia, and if they were the first fish in a new tank, ammonia may well have been the problem. Even if a fish "survives" the initial cycling, the ammonia or nitrite has likely damaged it internally and subsequent health problems and even death can occur.
Without a clear photo we are guessing at the white stuff; fungus in a filter is certainly not comon.
Why not take apart the filter and flush the stuff out. I would also highly recommend a decent sized water change to eliminate any pollutants that the water may contain. A water conditioner such as prime may be helpful in detoxifying and conditioning your tap water to make it suitable for your fish. But yes TEST THE WATER!

you should be able to find it at a local pet store.
When I got home the stuff that had been collecting in the filter had begun to blow out of it so this is a picture of a piece of it that sank to the gravel. Im going to clean the filter out tonight. You can see in the background the airstone at the bottom of the filter is completely surrounded in the stuff.
