I'm new to this excellent site. Great Q&A's - it's been really interesting and helpful. We are considering a new pond for our turtles (short necks, approx 4 years old). It is on the south-western side of our house. As the sun sets lower in the autumn/winter sky, the pond will receive less direct sunlight (summer/spring is no problem). It does appear that morning sun is key to get turtles away to a good start for the day. Would a turtle light (similar to that used in our indoor turtle tank) be a possible compliment to the direct sunshine that they will get? Any/all other commments/advice/suggestions gladly accepted. Many thanks in advance, Matt.
