Well, if you have a gecko that ingests the entire calcium dish in one sitting, as Allen's post indicates, I wouldn't put a calcium dish in his enclosure either.
However, for 99.9% of geckos....After making sure the gecko's gross calcium requirements are met by dusting feeders, I prefer to allow the gecko to fine tune his calcium intake by providing him a calcium dish. I think it's obvious that calcium requirements are different at different stages of the lifecycle (baby, juvenile, adult, gravid, etc.), and no one formulation of calcium supplement can be correct at all those different stages.
