I have a 5g nano tank and the filter is a powerhead that pumps water through a spraybar over the media.

The problem is that the water in the tank got suuper hot and it killed the little fish and snails I had in it.

It's brand new, my first time using it. Any way I can make it run cooler?

My last resortwill be to just mod the hood of this tank and remove the pump and use a nano HOB filter.

thanks :)
