Remember I'm old and been doing this for over thirty years , also a packrat , do not throw anything away. At my old house I kept from that in ground pond several PM190's I used as fountains. http://www.pondmasterstore.com/home/pm1 ... 0_kit.html
Just removed there media and set it up for turtle's ,worked great. Improvise !!! Would hide it with plants. Will not work in a small tank but for larger ones great do the room it takes up. Took fountain head off added hose with a DIY spray bar. Back then was only $30-$40 now about $70 but still cheaper than one with the turtle name on it. Also a DIY 5 gallon bucket Bio filter. Always had crystal clear water !
Now the FX6 all in one place mechanical , chemical , biological will make it easier in my young age. Haha! Cost is always a thing in this hobby but at this time in my life I broke down got one just for the ease of everything in one place. With one turtle now I really could go three four weeks on maintenance. But still do regular water changes in-between.
