I was holding two small red eared sliders for a friend for 2 days. after he took them back I took out the filter to help filter the algae out of one of my other fish tanks and let the turtle water sit in the tank. well last night I rinsed the tank and decor out due to to the smell and now it is back where it was dry and empty with a new basking area. I have a fan airing out the smell but it still reeks. I need to fill it again soon because I am getting a turtle this saturday. I need to know what will nuke the smell of the tank and be safe for me to fill the tank a day or two later.
thank you
