I have been reading through some threads about what kind of calcium to be used with your gecko. Some say use calcium with D3 some say don't,use calcium phosphorus free and then with phosphorus. I am confused:main_huh: I use fluker's calcium with vitamin d3 phosphorus free.I keep a small dish of it in the tank and dust the crickets 1-2 times a week with it. Am I doing something wrong?
