How To Choose The Right Magnetic Cleaner for Your Tank?

If you are an aquarist, you’re going to have to use a magnetic cleaner at some point. If you end up purchasing one from the recommendations below, the tool will prove to be one of the most essential over time. Now, in addition to high-quality magnets, some factors you need to take a closer look at before purchasing a magnetic cleaner.

In this section, we’ll discuss which magnetic cleaner will be best for your aquarium. Let’s discover more!

1. Tank Material:

Algae magnet cleaners come in a variety of types and options. Finding the right one requires experience, knowledge, and patience. Now, the tank material you’re aquarium is made of makes up the crux of this buyers’ guide.

Your aquarium could be made of acrylic or glass. Besides, thickness of the tank’s walls varies. Overall, the tank material needs to be within your purview. Algae magnet cleaners are very specifically designed. They could be made for either acrylic or glass aquariums. Some would help you scrap algae off both the types of aquariums.

What sets the each of these two types apart is the scrubber pad. Magnets for glass and acrylic aquariums are made differently. For acrylic tanks, the scrubber pad is composed of a much softer material. On the other hand, the scrubber pad for glass tanks features stiff material.

Using one of these scrubber pads for either of the tanks isn’t possible. For instance, if you use the scrubber pad made for glass aquariums on the acrylic ones, the pad would damage and leave scratches on it.

How do you know whether this scrubber pad is for acrylic or glass aquariums?

Simply touch it to discover. Scrubber pads made for glass aquariums will be hard or rough to touch – the feel will be similar to touching the “hook” side of Velcro. On the other hand, the feel upon touching the acrylic scrubber pads will be like touching the “loop” side of Velcro.

#Takeaway: Choose your algae magnet cleaner according to tank materials.

2. Scraper Blades:

Similar to scrubber pads, scraper blades will vary according to the tank materials. Choose metal blades for glass tanks, but plastic blades for acrylic tanks. Choose the wrong blade, you’ll regret until you changed the whole aquarium.

3. Magnetic Pressure:

The power of magnets needs to be strong enough for effective cleaning. Magnets clamping onto the tank wall isn’t a determiner of their strength. The magnets have to be strong enough to create necessary pressure for effortless cleaning.

4. Tank Wall Thickness:

Strength of algae magnets varies according to tank size. The thickness of tank walls determines how strong magnets should be. Obviously, the thicker the wall will be, the stronger the magnet has to be. So, if you own an aquarium with thick wall, you’re going to need a stronger magnet, and vice versa.

Final Thought

Pesky algae and unsightly dirt won’t stand a chance against the best aquarium magnet cleaner. If you want a tip-top aquarium and like to everything in and around it in optimal condition, then now’s the best time to keep a magnet cleaner.

As for my choice of tool, although I highly recommend all the magnet cleaners reviewed here, Aqueon Algae Cleaning Magnet is my top pick. The Aqueon Cleaning Magnet is perfect for removing nasty algae quickly and easily. Plus, its extensive versatility encouraged me to pick this fantastic algae cleaner.
