We were given 3 turtles, 2 aquatic and one box. I agreed on the condition of getting a crash course on how to care for them before we brought them home. Turns out the person we got them from really didn't know anything about them either. Now I am needing some help on caring for them. I have tons of questions, but right now the most important are 1) what can I use as "bedding" for the box? She sent home some ecodirt, but not enough and I can't buy it around here. 2) The aquarium for the other 2 she gave us is way too small, so I am needing other arrangements. Will a tote or stock tank work? 3) How do you use the filtering system from sounding like Niagra Falls if you don't fill it up all the way to give them a place to climb out and bask? I appreciate any help that can be given to me. Thanks!
