HELP! OK so I'm still not feeling confident with my final decision on what lights and dock lights to use over my new 6ft tank. The turtle dock is in the right hand side corner of the tank, there is a 15cm gap between the dock and the top of the tank. I'm trying to decide if I should put a 6FT long T8 UVB light over the tank, plus a dock heat lamp. (I was thinking a MVB)? Or a 4FT UVB light across the tank and two separate types of heat lamps, (UVB lamps over the dock?) Any advice on what is the best equipment that I should use would be much appreciated. There are so many different lamps for docks and I'm so confused.
