Howdy,
Over the New Year Holiday, I hauled, tied wire and pieces of cinder block to about 78 Christmas trees, then sunk them, vertically. From what I'm reading on this forum and the labor involved, I'd rather not do that again.

I see a plastic habitat sphere being sold on several sites, including Greg's site, www.lakework.com. I'd like to hear from some folks using them, Greg included.
How do sink them to keep them in one place?
I thought about attaching plastic fencing (in rolls at Home Depot) around one side to provide cover for smaller fish and sink several of the spheres almost touching each other.
Will beneficial organisms grow on the PVC, as it would on natural products, like trees?

Thanks In advance...
