ok I keep on buying these heat bulbs because they keep on blowing, I started out with a started kit tank then got a bigger one. But I also kept that small thing to screw the bulbs in, and now rather than using 50w bulbs I use 150. Should I get the bigger lamp (the black thing that you screw the bulbs in) should I get a bigger one cuz my bulbs keep blowing.
And how many hours a day should I keep the heat bulb on for?
