| The 3" non kink tubing is specfically made for the Oase Biotec Filter.
This heavy Kink-Free tubing dramatically improves flow. It's flexible, yet won't crimp or collapse around curves or if buried under the weight of stones and dirt. Constructed of high-quality, smooth-bore, corrugated base, its black color is ideal for use in water gardens as it is practically invisible underwater. It is virtually impenetrable to sunlight, inhibiting algae growth inside the tube. Fish Safe. Color is Black. Highly recommended over Black Vinyl Tubing. |
