yeah thers a few. Look online for a used octo skimmer they are the best bang for the buck. Also get a couple power heads to agitate the surface so it is in the water colum the skimmer will have a better chance of removing it most skimmer dont take anything from the surface just help keeping it from forming up there nut I dont care how good of a skimmer you get yoou need to agitate the surface anyway if it is forming up there
