Ricordia

There is another trick that works fairly well. I took a piece of 4" diameter by 2" tall pipe and glued screen onto the bottom of it. Covered the bottom of the pipe with oyster shells and put the rics in. Placed the pipe in a low flow area and let them attach to the oyster shells. Then they are easy to glue wherever you want. It takes a couple weeks for them to attach to the oyster shells.
