Do you use them? Think they are worth it? I have an old one that came with a used setup I bought. Finally tested it on my 125 tonight and it does an ok job of getting some of the brown algae off but not hardcore enough for the little green spots. The magnet on mine doesn't seem particularly strong so maybe I'm not using the right size for this tank or maybe its just a older design that's not as good. Just curious how many people are using them and how well they work.
