Magnetic Algae Scraper Ideas/suggestions

 

First, cheapest, most common, not sure how well they will work, the little one I have for my nano is none too strong.

 

Second, Algae free, not sure about the wood outside though it looks ok I am not too fond of Oak, probably stronger magnets??? replaceable scrubbers and felt, polishing kit available +++ Expensive! --

 

Third, Magnavore, appear to have stronger magnets, replaceable scrubbers and would probably work with polishing kit.  inside hangs over outside for easier corner cleaning.   May be lower profile inside.  Brushes available.  Expensive!--

 

DIY, magnets would be extremely strong, time consuming to make (though shouldn't be too bad) cheaper than even the magfloat, can make several, wood would match my stand exactly on the outside +++++, could use polishing kit, low profile inside and would hang over like the magnavore.

 

What do you all think?  What do you use?  I am tired of climbing in my tank to clean it and if I could do it from outside, I think it would stay cleaner and I would enjoy doing it as I could at least watch the fish and coral while I clean.  I like the idea of having it match my stand.  I am a little worried about the ratings on thickness.  My tank is 3/8" acrylic on the cube, 4mm glass on the  nano.

 

Thanks,
