Review on Advanced Aquatop Quartz Glass Submersible Heaters (50W-300W) by Kenny Marquez

I've had this heater for a few weeks now and after reading some reviews and doing my own research I think this is the only one Problem some people might have is from people. This heater has broken glass or something else due to improper use. To be on the safe side, I turn off the heat at least 15 minutes before doing water changes or anything to do with the glass coming out of the water. Larger temperature changes can cause the glass to break. Also, I just stand it upright with a plastic cover over the water just to make sure the water doesn't seep through. As long as you make sure the water level doesn't drop below the minimum I have a feeling this heater can last a long time. !
