Bests & Worsts Reviews from Amazon

I purchased this heater bc it had an automatic temp and shut off as a replacement for another heater that stopped working. I installed this product in my tank and within 48 hrs my betta fish that I had less than a year was dead. Within the first 24 hrs the heater made the water cloudy so I remove it. 24 hrs later my fish was obviously struggling and in the early morning passed. Im DEVASTATED!
