I have a 20G and have converted an Aquaclear Filter 50 filter into a fuge. I created a narrow baffle between the intake tube and the filter media housing area that hold floss. I have cheato in the large housing area, no live rock. Plenty of live rock in the display and was advised that LR in the filter could trap debris. I have read al lot about Chemi-Elite and decided is was a must have. Purchased today. Here is my question.. I understand that the media needs as much flow as possible through the bag but need to know where the ideal placement would be. I currently have the bag at the very bottom of the filter housing area with the Cheato placed on top and kept the floss in baffle area (floss wont fit there). Im not sure how the water flows through the filter and am unsure if there enough flow through the Chemi-Pure. Is the media placed in the correct area within the filter housing?
