+1 on the springtails, you hardly notice them and there great for cleanup.

i actually prefer java moss over sheet moss. mainly because java moss grows fast and i feel its more attractive.

another thing you could do its to use a different substrate. i cant stand eco earth for the same reason. i switched to a mixture i bought from josh's frogs, i forget the name, its very popular. has different mosses and contains carbon chips(which clean as well!)
