Tunze Nano Care Magnet review 0220.010

So I bought one of these for my Jewel Lido 120 liter nano as I had a few spots of Coralline algae on my front glass as you can see in the pic below. I'm a bit lazy in cleaning it, as a result the coralline has taken over. Although this is good because when scraping it off it will seed the rest of the tank.

I also bought a set of 3 steel blades just in case the plastic blades of the Tunze magnet wouldn't be able to tackle the hard coralline. (NOTE: Do not do this until you have read my stupid mistake about this).

Note: The nano care magnet does not come with a steel blade, these have to be purchased separately.

The unboxing...

Magnet box and pack of 3 spare blades.

The contents of the box: instruction manual, quality inspection sheet, the two halves of the magnet and a spare plastic blade.

Specs of the magnet and the glass thickness it works on

Here you can see the underneath of both sides, the scraper part that goes inside the tank has no rubbing pad to clean the glass as it sits a few mm away from the glass, the only part that touches the glass are the outer parts of the two blades. The outside half of the cleaner has two round felt pads for cleaning the outside of the glass.

Some close up shots showing the thin plastic blade. You can also remove one of the blades and use it as a hand held scraper. The plastic blades are very easy to remove, just give it a good tug and it pulls off easily.

Right, before we carry on, let me explain how the steel blades work, or in my case, don't work.

My own stupidity for not reading up properly and researching the magnet and how it works. I bought the steel blades thinking they would fit straight on. Wrong. It's a bit more complicated than that. Upon opening the blades I noticed they had two holes, yet the nano plastic blades only have one hole (as can be seen in an earlier pic). So I looked at the photo's in the book and noticed you had to have the longer plastic blades in order to fit on the steel blades. Right? Wrong!

[IMG]

Looking at this picture (again an idiot move for looking without reading), I assumed I would need the part numbered 3 (0220.0154). But seeing as I already had 3 blades (part numbered 4, 0220.155), I would just need the part numbered 2, 0220.0153. So I ordered the longer plastic blades and waited in anticipation. When they arrived I proceeded to unpack them and tried to attach the steel blades, however, there was no way theses two parts were able to join together. So I took to the internet to do some research and discovered that the only way to get a steel blade onto the Nano Care Magnet was to buy the "Blades set 86mm (0220.154)".

However, at the time of writing this, it would appear that this blade set is currently only available in the USA and Germany so I am unable to buy it.

Moving on...

Apart from that, the only negative aspect about the magnet is that it doesn't float. And it's really heavy so if you do lose control of it in your tank, be aware that when this falls it will probably decimate any corals that it happens to land on. I'm pretty sure this magnet cleaner will frag most of your SPS corals if it lands on them.

On to the cleaning.

I laminated a piece of A4 paper to hang in the tank to try and show the effectiveness of the cleaner. It works very well, taking care of 99% of the coralline algae, it only struggled on one or two small stubborn bits, with a bit of elbow grease it will eventually get rid of them.

[IMG]

Conclusion.

The magnet works very well and is very effective against all but the most stubborn bits of coralline, normal green algae was no match for the magnet. Build quality is very good, although if you have big hands like me then it is a bit small to hold, but it has ridges on the sides to help grip it. The space between the magnet and the glass is very helpful in preventing it from picking up small bits of sand and scratching the glass, but still be wary as there may be a perfect sized grain of sand that will still be able to be picked up, so don't go rambo on your sand bed, still use caution. I am happy with it, apart from the fact that it doesn't float, and it's very heavy so it will break corals on it's way down. I will update this review when the steel blade attachment becomes available to purchase.

If you leave the magnet in the tank overnight, be careful when you use it again or do decide to take it out, I left it in and the next morning I took it out only to discover 3 small Stomatella snails had made camp inside the plastic blades.

Any questions, please shout. Thanks for reading.
