Hi, need help fast please, my tank filter was not working properly so i took out to clean.It has a lot of sludge in bottom, can i throw this away, or do i need to keep some, as it wont go through my fine sieve.I have give the pads a squeeze & replaced the wool pad but will there be enough good bacteria if i throw it?
