Since everything in this hobby is expensive, I wanted to share a small money saving tip. I have a new 240 gallon and in a pinch I tried the magnet that’s currently in my 90 gallon (not thinking it would work very well). WRONG! This little $35 Hygger (medium size) magnet performed flawlessly! If anyone is shopping for a magnet cleaner, this one is awesome and handled the thick glass without skipping a beat.
