Ok, so I tried the gravel vac for the whole tank this time. But I think a lot of stuff got through the filter. I will add the foam to the filter. I am doing another gravel vac and wc tomorrow when I get a square bin I can hook the filter to without worrying it will fall off. I can check the water to see what is getting through as well. Sucking it up isnt going to do any good if the filter returns it to the water.
