JBL TopClean II. Effective prevention of scum formation (white layer on water surface). Ensures a clean water surface automatically and a higher concentration of oxygen in freshwater and seawater as a result.
Optimized floating body (more buoyancy, stronger Ridge, new internal form) and removable adjusting spindle. Effectively prevents pellicle formation (white layer on surface of water). Provides automatically a clean water surface and thus a higher oxygen content in freshwater and seawater.
