Hello, My name is Kim and my husband just recently left for deployment. I am now responsible for cleaning the turtle tank. We live in Japan and all the stuff we need for the tank is in Japanese. I am trying to figure out how much Tetra Aqua ReptoSafe to put in the aquarium. We have red eared sliders. Does anyone have any ideas? I can't find anything in English to help me figure this out. Please help. Thanks, Kim
