Good question Wood and thanks for the support all. Only thing I can think of is either lightning (which we did have some that night) or each curcuit is on a seperate kids bedroom.... so maybe they where up doing something they shouldn't have been doing.... as far as the heat goes I have found that acrylic holds heat very very well.... so the increase in temp without circulation is no suppricse to me...

Boomer, if you look in my gallery you will see a pic of my tank. In that shot you will see the two returns, where would you suggest I put an anti-siphon hole? Please I need advise, I though about the top of the T in the return, however it would cause water to shoot straight up and if the hole gets plugged there goes that idea...... any suggestions....
