What I have found to be the best solution is to keep the tank nearly full of
water, and to buy some of those large aquarium castles and climbing rocks
and to put a ceramic tunnel (or eel tunnel with holes in it) over the top of
the castles & rocks in order to create areas where the turtles can climb up
and sun themselves. A turtle should have an exciting environment, so I like
to put in as much climbing areas as possible, while giving them swimming
space. Those ceramic tunnels and wooden bark hiding places make great spots
for the turtles to climb on and get some sun or Lamp-light.
If you keep the tank mostly full, keeping the water sparkling clean is not
hard. My solution is to get one of those outside the tank water filters
whose capacity is about triple what the tank normally requires. Then I
change the filters every week or two. The water is always crystal clear.
Right now I have a two water filters running. One is a double-sized and the
other is the standard size, so between the two I have triple the amount of
filtration that a fish-only tank would normally need.
I also keep a lot of tropical fish in the tank, as this makes it more
realistic for the turtles, and the tank is more interesting to look at with
the various fish mixed with the turtles and the decorations.
