ive st up my viv and im rying to fine tune my temps. problem is the heat gradiant is massive. its only a 24inch lng tank. its down at 6 on one end and at like 90 at the other. ive just tried mving my heat mat across a bit sorta 3 inches (its an 11 x 11) ive moved it across to try and get the temp better will that work im not goign to put it in the middle but that could be a thought if the grad is big enoug with a hideon each side and ahumid in the middle. has anybody else got any other sugestions without spending a fortune on heat bulbs and more thermostats?
