Dr. Scott's basic message was to provide foods that have ratios of calcium to phosphorus that are higher than 2 to 1, and, stay away from things with more phosphorus than calcium. If you feed worms to your turtles, prefeed the worms with a low quality dog food (such as WalMart's Old Roy). Premium dog foods have too much Vitamin D and other minerals, and too little calcium. Instead of dog food, you can give the worms a commercial super prefeed, available at reptile-oriented pet stores.
Dr. Scott always likes to prevent problems before they develop. Hyper- or hypocalcemia and kidney problems can be detected by having blood work done on your pets. Every other year is frequent enough to detect problems before they become irreversible.
