Im planning on moving my tropicals into my 60litre hex tank, which would free up my 5ft tank.
good idea (even better if its 2ft+ wide)
I can use the current external filter on it, and the internal heater.
Yep this is perfectly fine, make sure its gutsy though
I know I need a UV light, does this have to cover the whole of the tank, so a 5ft strip lamp? andthen the spot lamp for heating the basking spot, can that just be a standard lamp?
nope the UV does not have to cover the entire tank, more coverage does help.
Nomal Spot lamp is fine, no thermostat is required as ifthe turtes get too hot they
go back to the water. Though dont get something stupidly powerful.
Oh an will it need a lid? because at present I dont have one??
Nope, mines lidless, if you geta problem with condensation, a platic condensation
tray up top can sort that out.
Make sure the heat lamp is pointing on the basking area (an area out of water for the animals
to warm up)
