Frag plugs
 

Can I get frag plugs in Calgary?:biggrin:

Red Coral should have them, although it does say sold out....

I've also seen them at other stores around town, OC I believe.

I like the 1 inch x 1 inch marble tiles that come in sheet at home depot or rona.You get like a 120 per sheet and its easy to peel them off the sheet and there reef safe.

You can mAke your own out of portland cement and stuff...check other diy sites or ask whateyecando.... Also rubble works great.
