Hi all,
I have an internal Eheim sponge filter in my tank which is cycled and has been up and running for
about 6 weeks.
I wondered if I should think about cleaning the filter or whether it is too early?
I'm worried that I might kill off the bacteria in the sponge as it hasn't been established long.
Any help is much appreciated.
Thanks
