P&s I agree.. Like I said my buddies a few don't have thermostats attached. Me personally I do..my 20 gallon has no UTH but my 29 gallon high has a UTH and overhead heat bulb ( reason is if I use higher than 100 watts y tanks drys out like crazy,so I have to use a 100 w which sent hot enough and use the UTH to give him heat under his hide)..under his hid is regulated at about 88degrees now and the air temp hot side is 85-88. Usually I keep under his hide around 83-85, but he ate today so I upped it to help with digestion... I take care of my boys
plus the hide in the 29 gallon is made of some thick resin or something,s heat don't get through enough,yet my 20 gallon got them re thin black plastic hides and they warm up real nice...
