Well now I remember one reason I dislike sand. My 6080 cleared one end, 4ft. away.
Yea, clowns are bad for fanning it clear, likely out of habit to lay eggs, even if they dont. When I set my 90 up again, I put their pipe/eggcrate home back for them again.

Even though some of the pipe has sand on the bottom, they lay their eggs on the top, so hopefully thats ok.
Now I need to stop it from blowing around. I can point my 1200gph Hydor straight at the stream pump and its just overpowered.
