Saim Flexible Airline Tubing for Aquariums, Terrariums and Hydroponics, Airline Tubing 300-Foot Spool

Very soft and thin walled tubing, works fine for my application. I use it with an aqualifter pump to maintain siphon in my overflow boxes for my reef tank. These lines are exposed to bright MH lights and clear/translucent lines tend to start growing algae and clogging up. This stuff is opaque, blocking out the light, and has had no problem with growths clogging it. It is very soft an flexible, and easy to route where needed, but the walls are so thin that it kinks very easily too. It also has a funky rubbery smell to it, but I soaked it in vinegar overnight, and then in a solution of baking soda another night, and it seemed to dissipate for the most part.

Great tune for the price and color

worked perfect
