"Flow" lily pipe: the invisible filter inlet and outlet
Do you use an external aquarium filter? Are you tired of those ugly, green filter tubes? Then the “Flow” lily pipe is an excellent alternative. You hardly see it in your tank and it creates the ideal flow. This lily pipe set (inlet + outlet) is made of laboratory glass. This makes it not only invisible (or almost), it is also much stronger than other glass.
True, you can find cheaper sets on eBay, but the glass of those is often three times thinner than this lily pipe. The result? At the slightest, the lily pipe breaks with all the consequences: your aquarium empties, your cabinet gets warped by the water and the floor is 1 big puddle!
Save yourself all those nasty situations and choose for quality, it will last much longer & you will have more fun with it.
