The biggest heat pad I can seem to find is 8" x 18". It's a 24 watt, rated for 50-60 gallons. Will that be sufficient for the garters in the 75 gallon tank, or am I gonna need something to supplement? Petco has the 24 watt on sale for $34, plus I have a 10% coupon!

I found a WTB ad on CL, so I'm talking to this guy about selling the 20L/stand/screen lid/uth. What he's offering will pay for the UTH and some chinese carry out! I'll have to swap everything over after work. Wonder if he'll help me move the tank to the other side of my LR??
