I'm new here and new to having a turtle aquarium. I'm a teacher and these were donated to me. I have 2 turtles, a RES and a Painted turtle. They were donated to me in a 10-gallon tank. After doing just a little research I found out that this wasn't nearly big enough. I was able to get a 55 gallon tank today very cheap but now need a good filtration system. Would love to hear what is out there and hopefully get something reasonably priced. I see that I've missed some good prices on a few eheims and fluvals so message me with what you've got. Thanks!
