I just found a really cheap fx5 filter someone is selling online but she says it's like new. I don't think there would be a problem, but I just wondered what anyone else thought about using a 2nd hand filter on a turtle tank? I'm moving soon and want to get everything together for my 155 gallon tank as soon as possible, and if I don't have to spend $300 for a new filter, that would be great.
I am currently using a rena xp3 on a 55 gallon tank.
