My comment regarded risk in the abstract. It was not refering to your kids pond ,or Gator, or anyone doing an expir. with knowledge or anyone using tilapia or TS. It is simply that the result of using tilapia or TS or for that matter crappie are known while with GG you don't know what you end up with. For most pond owners starting over is not an acceptable risk option. For small ponds or those with knowledge renovation may well be an acceptable risk. ewest
