Buy Tetra EasyCrystal Cartridge for EasyCrystal Filter 250/300, for Fast and Clean Filter Replacement Online in Indonesia. B000XA6RVI
Purigen - I am running a Tetra Easycrystal Filterbox 600 which came with my tank (unfortunately since it's freaking huge). I wanted to put some Purigen in there, but where do I put the bag? Should I replace the current bag with the filter material in it? Anyone ...
