Has anyone seen the new bigger ones. they have a 8 now that's like 3200GPH. It's in the new dr.forst and smith book. I would lov eto have one or two for my 585 but I don't think they will hold my glass it's to thick
This is what the manufacturer claims about the #5 ~ #8 's...
The magnet can safely hold Koralias applied in tanks with glass (or acrylic) up to 20mm (.8") thick. The magnet is specially covered to prevent corrosion
