View Full Version : Evo Koralia 4 upgrading magnet

07-19-2011, 06:16 PM
Has anyone ever tried to use a stronger magnet or modified one using a stronger magnet. I have a tank that has 1" glass that we are trying to use the powerheads in but the magnets are barely strong enough to go through that thick of glass. I know that there are the magnums but are the magnets any better on those?

Any suggestions upon how to make it work would be greatly appreciated.
