Im setting up spike's new 75 gallon tank, for uvb i am using the slimline 50 uvb fixture and the repti sun 10.0 for the bulb. And for the heating im not sure what wattage and where i should place the bulb/bulbs. I am thinking of buying 2 100 watt bulbs and placing them on 2 parts of the enclosure one on the basking spot and the other just to get the temperature up. Or should i just get one 150 watt bulb on the basking sp and the uvb being 3/4 of the tank.
