hello,

I am currently using the DAZS-80 Whirlpool Outside Hang-on Filter for my mini tank for nearly a month. So far my red cherries were still alive and swimming well. I've read the cardboard box for the filter says the internal components such as the bamboo carbon, bio-mat and compressed mat have to be changed about 1-2 months. Can anyone points me to the shop selling the internal parts to this hang-on filter?

thanks!
