Please help me with cracking tank

[Heatheranne]

It may be that the light is too close to the glass. When you mist with the cool water it can hit the hot glass and it may crack due to too quick of a temperature change for the glass. You'd be surprised how much heat a uvb can give off. Try elevated the light higher so the glass doesn't get too hot. I am guess it cracked at the top?

Has anyone ever heard of some how making the top into a screen? Some how cutting the glass out of the top and putting in a screen?
