Quilt batting is amazing
After a week of taking run off from torrential rains and then losing half the water due to the waterfall box leaking, and then having me use the half-empty opportunity to dig out and restack a section of retaining wall that was falling in, and then having me manage to dump one of my marginal baskets into the water trying to take it out... well, it was a cloudy, murky, mess.
I put quilt batting in a plastic basket, put that under the output of the waterfall filter. This morning my water was crystal clear and I could see all the way to the bottom.
Had a lot of fun watching my goldfish swimming around. My misadventures of garden ponding didn't seem to effect them any :) They really like to hang out under the waterfall and nibble on the rocks.
