I wanted to give the turts more water to swim in. I bought some UVC pipes and attached them under the Zilla basking ramp with some aquarium rock epoxy. Then I moved the small internal filter and heater to the back wall and stacked them up for the ramp to rest on.
When it was all set-up, I noticed that the PVC pipes were big enough for the turtles to fall into and that they might get stuck inside and drown, so I stuffed some unused aquarium air tubes in them.
With the basking spot a lot higher than before, I got worried that they might be too close to the heat/uv bulb. I put to use a lamp stand to raise the lamp higher.
The tank now looks incredibly different, and the turts certainly enjoying having more swimming room…
