One of our tanks is a 50L roughly 2x1x1ft tank with a sponge filter, lots of cabomba and a few other plants, drift wood and 1 male siamese and 2 females, 2 bronze corydoras and 2 whiptails. I am getting concerned though cause all through the tank is greyish white fluffy scum. I am wondering if this is a bacterial bloom. If it is, How do i treat it? If it is not, Then what could it be? And what does a bacterial bloom look like?
can someone please help me, i do not want it to get too bad that it will start killing my fish. The tank has been running fine for ages but all of a sudden (or so it seems) it has this fluffy stuff everywhere and especially on the surface of the water and round the plants.
pH and nitrate levels are fine.
Any ideas??
Thanks Loopy
