Title: Works great for 3 weeks... then try getting a refund!!
Review: It worked for 3 weeks, then just stopped. I called the TetraFauna people to ask for a refund and the guy told me that I needed to buy a bigger heater- it is not strong enough for a 30 gallon tank unless your room temp is 72F. So this only heats the water from 72F room temp to 78F. 6 degrees is all shes got. After that it just dies, apparantly.I've read other reviews off of amazon and this has horrible reviews-- look elsewhere for a good tank heater.
Is the review positive or negative?
