This new gravel cleaning system comes with three extendable pipes allowing an adjustable cleaning depth of 30cm/12", 40cm/16" and 60cm/24" – ideal if you have several tanks of different sizes. It features two clips – one for the aquarium and one for the bucket – and has a shut off valve for ease of use, meaning that if you need to go and empty your bucket during cleaning, the syphon action won't break. The Aqua Clean also features a quick start system and even comes with an attachment for cleaning the bottom of the Juwel filter.
