    so my freshwater indian dwarf puffer has a fungal infection so i picked some stuff up from my lfs; the problem is that i only have a carbon filter for the sponge filter i have running and i don't have any cycled filters i can use right now. if i take the sponge off will it mess up my cycle? this is the first time i've had to use any medication for a fungal infection and i just want to make sure it works right. thank you!!

    I would put carbon filter in a bowl of your fish water and run filter without it while meds are working on tank.

    Is the carbon inside the sleeve of the sponge? If so, make a slit along the top of the sponge with scissors, empty the carbon out and place back into the filter.
    And, Welcome to fishlore! :)

    i actually found a spare hob filter that I'm running now with cycled material in it :) the sponge itself was a carbon sponge, which, was kind of weird to me when i was buying it but it seems to be working fine. Also, thank you!!
