My tank has been running for almost 2 year and now i wanted to change the filter setup, i would like to used natural filter ( live rock and live sand ). Possible to take out all the sponge from the sump and change to LR & LS and used filter sock.
PS: i don't like to see this sponge in there and don't like to clean the sponge.
