At a glance
Buy a cleaning magnet when you want to handle viewing-panel care between service visits and the aquarium supplier approves the exact cleaner for the finished tank. Match it to the panel material and thickness, check that you can move it around the intended viewing area, and ask for a demonstration. If your service team handles all cleaning, clarify whether you need your own tool before adding one to the order.
Would you enjoy keeping the view clear between visits?
The new aquarium is taking shape, and the accessory list includes a magnetic cleaner. You like the idea of tidying the viewing glass without reaching into the water. But if a specialist is already coming to look after the tank, will this be useful equipment or another purchase that sits in a cupboard?
We'd add one when you actually want to do that part of the care and the supplier can show that the chosen tool suits your finished aquarium. If you want a fully managed arrangement, ask the service firm whether it supplies its own equipment. A cleaner should fit the ownership routine you want.
Choose for the panel, rather than the aquarium capacity
A large tank description doesn't tell you which cleaner to order. Ask the fabricator for the viewing panel's material and thickness, then have it approve the exact cleaner and attachments. Keep that recommendation with your aquarium records.
TUNZE, for example, specifies its Care Magnet strong 0222.020 for glass between 15 and 20 millimeters thick. It expressly does not recommend that cleaner for acrylic. Those limits belong to the named product; they aren't a buying rule for every magnetic cleaner.
If your quote says only cleaning magnet, ask for the manufacturer and model. Don't assume a stronger version is a better upgrade. Let the aquarium supplier match the tool to its panels, especially when the design has different materials or an unusual viewing shape.
Can you move it where you want to clean?
Look at the final aquarium with the designer, including the surround and aquascape. Ask them to show where the outer handle can travel and whether the inner cleaner has room beside the décor. A tool that looks convenient on an open display may be awkward in a recessed installation.
Say the main viewing pane sits close to a projecting cabinet edge. Before buying, ask for a demonstration of the proposed cleaner in that arrangement. If it cannot reach a useful part of the view, find out which approved tool or service task covers that area instead.
Our glass-versus-acrylic guide helps with the tank material decision. Here, the practical question is whether this particular accessory works with the aquarium you've chosen. You shouldn't need to change a finished surround just to accommodate a casually added cleaner.
Ask for the care demonstration before you take over
Magnetic cleaners still need care. Custom Aquariums warns buyers to check its Mag Float cleaning pad for sand, gravel and other debris before use, and not to use that pad on or near silicone seams. TUNZE also warns that contamination can cause scratches even with its cleaner's design.
Have the installer demonstrate the approved product on your tank and explain the manufacturer's restrictions. Ask what you should inspect, where the tool may be used, how it should be kept, and when to stop and call the service team. Follow the directions for the exact product rather than copying another owner's routine.
If household staff will use it, include them in that handover and label the approved parts. The convenience is worthwhile only if everyone knows which equipment belongs to which surface. This guide doesn't prescribe a cleaning technique or frequency for your aquarium.
What will you replace after the initial purchase?
Compare the supplied cleaner with its ongoing parts. The current TUNZE product lists spare plastic blades in the box and separate replacement blades and felt parts. Ask the seller which items apply to your chosen model, how you obtain them and what is included in the price.
You may prefer a tool with an explained replacement process over a bundle of extras you don't understand. Ask the service firm whether it supplies or replaces wear parts, and whether there is any reason to buy spares now. Future price and availability need their own confirmation.
Also settle who owns the tool. A cleaner supplied by the maintenance firm may travel with its technician; one in your aquarium order may belong to you. Our maintenance-plan guide covers the wider service agreement. Use it alongside the accessory decision so that both proposals describe the same arrangement.
Buy the tool for the care you want to do
Ask for a specific model, approval for the finished panels, a demonstration in the actual layout and a clear parts-and-care handover. If those answers are complete and you want to keep the view tidy yourself, the magnet has a useful job. If you would rather leave cleaning to the specialist, make that preference part of the service proposal.
Our vetted aquarium experts bring field experience and provider relationships. Tell us which parts of ownership appeal to you and which you'd like handled. They can help you compare the accessory order with the service arrangement, while the fabricator confirms exact tool compatibility.
