500 Feet Deep Jungle Black Flexible Airline Tubing for Aquariums, Terrariums, and Hydroponics (500 Feet)

Quality product, not stiff. Really easy to work with. No fear of this getting stiff over time and cracking. Perfect for hydroponics, since its opaque.

I put these air lines in my fish tank about 2 weeks ago and they are the only thing in the tank that have changed color and got some sort of sludge on them

works great

A+

Easy to handle due to soft texture

Perfect

Excellent

Love color in black sand

If you have a super cool aquarium setup, or a small dwc grow, this is good buy. Same black tubing as sold elsewhere, just at a slightly lower price than their competition. If i needed, Ill definitely buy more.

Does great and has no light leaks
