looking for easier cleaning solutions for 3 res adult turtles. currently i have 1 big female in one big rubbermaid and 2 smaller males sharing another large rubbermaid. i want to figure out a better living space condition and a easier way to keep their water clean. i was wondering if i got a large plastic crate (such as image) and put some sort of wire mesh barrier in between the big crate so i can separate the males from the female (i dont need anymore turtles...and the males try to harass and rape my poor female :[ ) i can give all 3 of them more swimming space and hopefully be able to keep the water cleaner, longer with only 1 powerful filter rather then 2 whatever filters....so my question is, will a pond filter and a larger swimming space (thus more water) help the water quality cleaner longer? also i will have to move this crate outside in the backyard.
