So I purchased a 150w Aquaclear heater.
First thing I noticed, it's very difficult to keep the heater in place. The suction cups slide when doing anything in the tank. The clips seem 'too loose' around the glass cylinder.
I know they aren't full time heaters, and shut off when the temp is reached, but why does it always let the water drop well below the temp before turning on?
Sometimes the water is room temperature, (and it's fall here).
Sometimes it's because the heater randomly slips out of the inconvenient range of minimum/maximum water height, but other times it's still in the right position, but doesn't turn on until I fiddle with it or change temperature.
Does anyone else have problems with these?
