Prevents turtle shell bacterial problems!
on July 9, 2012
I always add a "turtle tablet" when I do a water change for my red-earred slider turtle. It prevents the shell pitting and discoloration caused by bacteria. The active ingredient is Sulfa.
One time I didn't put a fresh tablet in the water and the turtle's shell became pitted. I did a water change and added a fresh turtle tablet. In a few days, the shell cleared up.
