The TMC Lily Pipe Outflow for external filters provides the ultimate in cool. When you use glass pipes it adds to the overall improvement to your aquascape because it's less obtrusive than the standard green plastic pipes common with most external filters. Your focus remains on the aquascape, instead of your equipment which can sometimes catch your eye.
A key design of the Outflow is the funnel - unlike most outlets which push water out in just one direction, this outflow spreads water around due to the clever design. This means that more nutrients are dispersed to a wider range of your plants and as a result will help them grow. This wider spread means less dead spots too so it will help algae issues. Not only that but CO2 is also more widely distributed, so you can see already the major benefits of glass outlets compared to standard equipment that come with most filters.
Another feature of this outflow is the way it can remove film from the surface of your aquarium. If your filter is powerful enough and you position the outflow just at the right height from the surface, it will create a whirling effect, sucking up any surface film without too much water agitation. Of course if you wanted more water agitation, you can simply lift the outflow up a little more.
Suitable for all filters which use 12 or 13mm tubing.
Tip: If you struggle to get your filter tubing on a glass pipe, use a hair drier to heat the tubing up prior to inserting - do the same if you need to take it off for cleaning. This makes the tubing supple and it can then slip onto the glass easily.
