Jeramy, I plan to put LR and cheato into there.
Toby, yeah, I looked at how the water fell after removing tab, calculated the flow rate, bended the plastic canvas to allow space for water movement and have a pocket for carbon filter. I went to Upscales and saltwater Fantaseas and Petco to view the sizes of carbon baggies and sized it that way. Now the water flows through the carbon rather than around it. Of course, it's not great flow but the way I curved it makes for significant quieter flow.
