I have thought of using bio-sponge but can't seem to find a piece with the correct dimensions.
Are there alternative mechanical filtration media of a suitable size?
Thank you! |
Filter wool should be replace or wash periodically.
Black sponge is able to last longer than filter wool, but u still have to wash it periodically.
For my IOUS tank, i would put filter wool as the first,sponge as second, and japmat as third for my mechanical filtration.
Wool is replace weekly or bimonthly.
Sponge is wash monthly.
Jap mat wash bi yearly.
