Excellent company with super fast delivery on my new aquarium! Delivery driver very helpful also helping me get it into the house! I chose not to add middle door on the cabinet and add baskets this is not how the juwel Rio comes as standard & also I changed the bulb!

Online order. Everything was clear and easy to understand with ordering. Biomaster 2 was delivered quickly and well packaged. I did have a query over the piping. I called the contact line which was answered immediately 👍. The guy I spoke to solved my query straight away in simple A,B,C walkthrough step. Great experience and will be back. Paul
