I don't use a filter on my tank, i have a 75gallon AGA and the only filtration is my biological media on the rocks, sand and on the pre-filter to my maxi-jets. obviolusly with no filter there are gonna be water changes and the clarity of mine is fine, but it is a hassle cuz some of those days it's like, yay i get to drain and fill the tank back up, but when it's done it's well worth it and iv'e been doing this method for the past 4 years now, my turt has seen 10 gallon, 20 gallon long, and was recently upgraded to a 75gallon AGA and will in the next few months be upgraded to a 210gallon AGA, all using my cleanin method, also as i'm doing the water changes the sand bed also gets mixed around and all old food particles and turtle waste are pulled out. Here is my baby in her 75Gallon, in the vid there was only a Maxi-Jet 600 in the top back right of the tank, but I have recently added a Maxi-Jet in the top back right and the Maxi-Jet 600 was moved over to the top back left(not seen in video)
