I use clean paper towel folded into fourth's on inside glass each week (doesn't allow build up) if cleaned each week.
Use same on outside glass with glass cleaner (not on inside).
Stopped using algae magnet's when I went to sand substrate's (too easy for sand to get into magnet type scrubber's.
May give the Mr. clean block's a try, they sure don't clean crap in kitchen or bath.
