Algae will always thrive if sunlight and an exposed nutrient solution is available. That is why it is crucial to use the correct hosing when it comes to hydroponic systems and or outdoor beer dispensing systems.

Prevention is the best cause of action when it comes to algae control. EVABarrier LightShield Black should be your number one choice of hosing when setting up your indoor or outdoor growing space.
UV stable hosing that will not kink or burst under normal use.

EVABarrier Hosing
Outer Barrier
The outer barrier has accurately extruded tolerances and made from an EVA material. It also seals well when used with various John Guest, duotight or other push in fittings.  The outer barrier gives the tubing excellent kink resistance so the line is able to bend around a tight radius without kinking.

Inner Barrier
The inner barrier is made from a proprietary polymer that has excellent gas barrier and now with LightShield technology an excellent UV and Visible light blocking properties.
The significantly better barrier properties means your beverage is better protected from oxygen and also has a better barrier to CO2 loss.  So your beer will stay fresher for longer and not lose carbonation like other beer line types.  In some beer line types you may notice that the beer sitting in the lines starts to taste flat and/or oxidised when sitting in the lines for an extended period.  EVABarrier tubing is significantly better in this regard and you will notice a significantly improved freshness of your beer especially if it's been sitting in the lines.

Due to the high density and smooth nature of the EVABarrier inner barrier the tubing internal surface is super smooth and almost completely impermeable.  This makes it difficult for bacteria and other microbes to attach to the inside surface of the tubing.
