I inherited some turtles from my dad who was old school... ie. had them for 10 years, no basking spots or any way to get out of the water, no UBA/UBV lights, just regular tube lights etc. Anyways they survived and I have them now. I have currently given them a way to get out of the water by piling rocks to one side and placing halogen lights above to bask, and replaces the 18" tube lights with the proper UVA.UVB lights.
So heres the deal they are big guys in seprate tanks, ones 9" long and the others 6" long and the rock piles are taking up valuable space and they cant truly get dry dry there. so I want to make an above tank basking area then fill the tank with water, that way they can have more swimming area and a place to bask.
What I need to know if a couple of things, will filling the tank up with water so they cant touch the bottom be ok, or will they drown since they arnt used to being in very deep water
Also the only way for me to make an above basking is to take off the canopy hood with the tube lights and mount the basking platform there...... but then I lose my UVB/UVA light over their water, now unless I have it wrong, dont they need this light on them all the time when they swim or is it only when they bask and in this case i could have another uba uvb light next to my basking heat lamp on the upper basking area and that will be enough for them when they bask?
Thanks for any clarification you can offer!!!
