Hi, here in Gurgaon, India, dust is a very big problem at winter. Now I am getting, a thick film of dust layer, floating. I am running Eheim 2217 for 24x7 but as it's a planted tank there is no surface aggitation. Now my question is, how to do a surface skimming to remove the dust layer? Is it possible to use a Marine surface skimmer to do this job at night for some time or is there any otherway to handle the problem? Will be waiting for your input.
