Bev C Posted March 31, 2022 Share Posted March 31, 2022 I have 2 of the ACO sponge filters and i have nerite snails .. I use a razor blade , toothpick and a toothbrush to clean of rock, wall and wood … and most times i do not mind the eggs from the snails they do a wonderful job cleaning but the blade or toothpick or brush will not work on the sponges i have tried boiling them and still no luck to get them off ,, any way to clean these i would hate to replace my sponges they are still good and doing a good job but looks awful with white eggs covering the black sponges Link to comment Share on other sites More sharing options...
