OK, I've had it going for almost 24hrs, it works great, i'm gonna continue using it!
It maintained the temp exactly as it was when it was it the tank! I though there might be a slight drop in temp, but there seems to be none!
I'm pretty happy I don't have to hide the heater with plants anymore!!
Kherman, your cap idea sounds OK but I really don't want any chance that it would overflow!
With the 1.5" output the is defiantly no chance of that happening!
Yeah the output is about 1/2" into the water... not noticeable!
