The JBL Autumn Competition 2021

Let the dazzling colours of the golden season and its hours of sunshine into your aquarium! Instead of dead leaves and shades of brown, we’ll supply you with brilliant green and red tones lit up by the autumn sun. Win a professional CO2 set with control unit and a 2-year supply of CO2. This way you can get your most demanding plants to shine and show their best colours in your home aquarium. The prize has a value of over 650 euros.* But don't worry, no participant ever goes away empty-handed, because once again we’re offering attractive consolation prizes for each participant. The JBL Team has something in store for you too. Let us surprise you.

It's that simple

Simply answer the question by October 15, 2021 and press the "Participate now" button for your chance to win the JBL PROFLORA CO2 PROFESSIONAL M SET including pH control and sensor and a 2-year supply of CO2 worth over 650 euros. A winner will be chosen at random from all participants and will be notified of their prize worth up to 665 euros? by email. All participants to successfully complete the three steps will automatically receive a consolation prize by email at the end of the competition period.

Unfortunately the competition is finished already. Shortly you will find another competition here. Simply look in again later.
