algae magnets

[sumpfinfishe]

I use a rare earth and will never go back to the cheaper ones.
Mine cost about $60 but it has replaceable felt and cleaning pads, not to mention this magnet kicks butt on strenght. It holds to the glass like no other and is great for going around corners. It's so strong that you can put it on either side of one hand and it will stick to the front and back of your hand-watch the fingers though! With this strenght I only need to make one pass on the glass to see crstal clear.
