I have a 115 gallon tank that I am moving my two res to this week. My tank is stand is one piece including the top, where the tank slides in from behind. I purchased a powersun 160 flood for the tank. I have read alot of the other posts and wonder if I can keep it 16" from the dock. Any suggestions? Thanks

Here's a pretty good link on the various strengths of MVB's and distances.

Per this site, the recommended distance is 18 inches from a 160 watt UVB flood.

Also, the packaging for the bulb should indicate the safe distance.

Double check the heat on the basking area too. Those MVB's are pretty powerful!

i have a 100 watt UVB light, how many inches should i keep it from the dock for 3 RES's ?

Is it a flood light or spot light?

100 watt uvb light? What model are we talking? i think with the 100 watt reference your refering to a basking light. I have mine about 14" away and it's a basking light

i have this bulb

with a clamp cover. how would i mount the lamp 14" from the basking area?

I hope you know this isn't a mercury vapor bulb---it says it's full spectrum, but it doesn't say it emits UVB rays. You could have used a regular lightbulb for heat instead of this bulb You need to make sure that 14" away is a good distance, and to do this you need to check the temp with a thermometer. A basking area temp of 88-90F is good. Your turtle still needs a UVB light, though.

Marisa is, of course, right on here. The light is nothing more then a basking bulb. You will still need to provide a UVB light ontop of that.
