I got my moms fluval 404 and it works perfectly n all. Only worry i have is that there is still salt from it. I rinsed it with water and scrubbed it with a metal sponge. I did all my normal stuff to the water and such, but im not sure if its safe for my turts yet. Im pretty sure the DBTs will be fine because they can adapt to the salt, but the RESs n the pleco arent. I also put back in my plants and they seem to be doing perfect.
