Thanks, Chip.
The local Wal-Mart is trying to get rid of their summer stock of kids swimming pools. Could I suspend swim noodles around the edge and grow stuff in that?
I need an idea for a substrate that wouldn't fall through the root holes, and wouldn't float out of the top of the pool, and would support a cattail root structure. The cattails should grow so rapidly that they would suppress algae formation by serving as a nitrogen sink. Then I could pull it to shore twice a year and remove and discard 3/4 of the cattails.
In the mean time, I've got shade for the fish.
I'm thinking of doing this in my Dad's little pond. It's receiveing about 24 ounces of food each day. I'd need enough plant growth to offset this nutrient load.
