Hi all im pretty confused at the moment my filter sponges and pillow stuffing keep turning red in my 55 gallon african tank. the pillow stuffing is a sort of pinky colour its the sponge thats fairly dark. it is fairly old and has been reused a fair few times. :roll:
i would love to know what is causing this. :x
