Get quick answers to common questions about Red Sea Aquariums

What are Red Sea Aquariums?

Red Sea Aquariums are premium, reef-ready aquarium systems designed for both beginners and advanced marine hobbyists. Known for their elegant design and high-quality construction, Red Sea tanks are engineered to support thriving reef environments with integrated filtration, lighting, and cabinet systems. These aquariums make setting up a successful marine or reef tank easier by offering a comprehensive, plug-and-play solution.

Why should I choose a Red Sea Aquarium for my reef tank?

Choosing a Red Sea Aquarium ensures that you are investing in a system specifically designed to support marine and reef life. Red Sea aquariums are known for their superior build quality, modern rimless designs, and attention to detail. They come complete with integrated sumps, automatic top-up systems, and piping that is pre-assembled for easy installation. Whether you are keeping soft corals, LPS, SPS, or fish-only systems, Red Sea aquariums provide an ideal environment for long-term success.

What Red Sea Aquarium models are available at Charterhouse Aquatics?

At Charterhouse Aquatics, we stock a wide range of Red Sea Aquarium systems. Popular models include the Red Sea REEFER series, which offers customizable reef-ready tanks in various sizes to suit different spaces and budgets. We also offer the Red Sea MAX series, which comes as a complete plug-and-play solution with integrated LED lighting, filtration, and circulation systems. Whether you are looking for a compact nano aquarium or a large display tank, you will find a Red Sea model that fits your needs.

What is the difference between Red Sea REEFER and Red Sea MAX aquariums?

The Red Sea REEFER series is designed for hobbyists who prefer a customizable system. It includes the tank, cabinet, and sump filtration system but allows you to choose your own lighting, pumps, and other equipment. The Red Sea MAX series is an all-in-one plug-and-play system that includes integrated LED lighting, filtration, and circulation equipment, making it ideal for those who want a complete, ready-to-run marine setup straight out of the box.

Are Red Sea Aquariums suitable for beginners?

Yes, Red Sea Aquariums are an excellent choice for beginners as well as experienced aquarists. The Red Sea MAX series is particularly popular with those new to reef keeping because it includes everything needed to get started, from lighting to filtration. The REEFER series offers more flexibility for hobbyists who want to select their own equipment. Both series are designed to make the setup and maintenance process as straightforward as possible.

Do Red Sea Aquariums come with a sump system?

Most Red Sea Aquarium models, particularly the REEFER series, come with an integrated sump system. The sump is located in the cabinet below the tank and includes a filter sock or filter cup, skimmer chamber, and return pump section. Some models also feature an automatic top-off system to maintain stable water levels. This design allows for superior filtration and makes it easy to add additional equipment such as reactors, refugiums, or UV sterilizers.

What sizes do Red Sea Aquariums come in?

Red Sea offers a wide range of aquarium sizes to suit different spaces and needs. The REEFER series starts from compact models like the REEFER 170, which is ideal for smaller spaces, and goes up to larger tanks such as the REEFER Peninsula and XXL models that are suitable for more advanced reef displays. The Red Sea MAX series also includes models ranging from nano tanks to large, fully integrated systems.

Are Red Sea Aquariums reef-ready?

Yes, all Red Sea Aquariums are reef-ready. The REEFER and MAX series are specifically designed to support coral reefs, providing excellent water circulation, optimal filtration, and proper lighting options. The systems are also built to accommodate advanced reef-keeping equipment such as protein skimmers, dosing systems, and auto top-off units.

Can I customize the equipment in a Red Sea Aquarium?

The Red Sea REEFER series is designed for customization. While the tank, cabinet, and sump are provided, you can choose your own return pump, protein skimmer, lighting, and other accessories. This flexibility makes it a popular choice for hobbyists who want to tailor their system to specific livestock and preferences. The Red Sea MAX series includes all necessary equipment pre-installed but still allows for some customization and upgrades if desired.

Are Red Sea Aquariums easy to set up?

Red Sea Aquariums are designed for easy installation. The plumbing for the REEFER series comes pre-assembled with quick connectors, so no gluing is required. The cabinets are sturdy and feature leveling feet to ensure the aquarium is perfectly balanced. The Red Sea MAX series takes convenience a step further by providing a complete plug-and-play solution with all equipment included and ready to use.
