Frequently asked questions (FAQ)

These are the most common questions we receive from our customers on a daily basis. If you cannot find an answer to your question, please contact us via email Before doing so, please check this list carefully.

  • You can fill a form on this page, and request a free quote, or send us an email to The email should contain internal measurements of your aquarium, number of additional rocks and information about the model you would like to buy.

  • There are two types of backgrounds- regular and slim models. Regular backgrounds are made of a special type of expanded polystyrene, suitable for wet environments and coated with several layers of special protective materials. Slim models are made of rubber mixed with special ingredients and coated with protective layers as well.

  • Standard backgrounds have one or more chambers made for suction pipe and heater. Water enters those chambers through naturally looking cracks or a space between the glass and the background. Freshwater outtake is to be placed over the background. The aim is to hide all that unattractive plumbing behind.

  • Standard Aquadecor backgrounds consist of several pieces for a simple and easy setup. Slim backgrounds come in one piece, but are very flexible and can be easily inserted in an aquarium with any kind of reinforcements.

  • All backgrounds can be accompanied by additional rocks in the same color as the background. There are two types of bottom rocks- floating and non-floating. Floating rocks need to be glued to the bottom, while non-floating are much heavier and can be put in an already setup aquarium.

    Overhanging rocks are placed under the reinforcements and are held by the water pressure. They don’t move, even though they don’t require gluing.

  • All backgrounds are 100% neutral to all environments and are completely safe.

  • The setup is very simple and you will receive instructions on how to do it. Beside that, you can visit this page and watch a video on how it’s done.

  • Backgrounds are very durable and it is highly unlikely that this will happen. However, if it does happen, just send us a photo of a damaged background and we will replace it with a new one.

  • Yes, you will receive payment instructions as soon as you make an order. Beside PayPal, we accept payments through bank transfer.

  • It usually takes around 10 business days to make a background and around 6-8 business days to deliver it. This, however, depends on the size, model and other factors.

  • Each background that can be seen on our website or social media can be made again in the dimensions of your aquarium.

  • The width of the background depends on the width of your aquarium. You determine the maximum thickness of the background at the most prominent areas. We always make sure to achieve the best 3D effect without taking up too much space.

  • Yes, but in that case, the background should be coated with a few additional protective layers. If you want to order a background for a marine aquarium, please don’t forget to mention that detail while making an order.

  • Sidepanels are parts of the background that cover one or both sides of the aquarium. If you have an aquarium in a wall, or one side of an aquarium directly facing a wall, it would be a good idea to cover that side as well. If you choose to cover one or both sides, please contact our team at
