Its often the smallest changes that make the biggest difference. And this Silicone Airline is a great example. The supple and smooth silicone really reduces the noise level in your airline and pretty much eliminates the kinking which causes irritating airflow restrictions. Its non-obtrusive, non-toxic and fits easily to any standard air accessory. Wed suggest, however, that you use it with other Interpet air pumps and accessories for the very best environment for your fish and plants.
