:/ we get a toilet scrubber and keep it out at the barn, and EVERYDAY when we're watering we scrub the buckets, and it seems to keep it down... we also dump waters out when their below half and do a complete cleaning of them or if they are dirty..... :]

I do the same but our summers are 105 even if its all the way full the water gets warm. I never thought of a toilet brush I use a scrub brush but it doesn't reach everything... 99 cent store here i come! I also use a mesh collender(spelling?) to remove debris.(yey 99 cent store!)
