Magnets !

[Riotfishdude]

i dont see the need for magnets like these in a properly kept setup,if you have gunk,algae's growing on your glass, wouldnt the best thing to do be upgrading your skimmer?,i run an Aerofoamer on my 130g FOWLR tank,messy fish,no algae,clean my tank glass weekly with $10 Hagen magnets,even though theres nothing to clean,no magnet is going to take off coraline,i use a razor blade (good ones,wife is a hair stylist),these magnets are pretty expensive when that money is better spent solving your algae problems.....JMO for those looking to drop big $ on glass magnets...spend it on a skimmer!.......Riot......
