Lol I have a 300w heater keeping my 1000l tank stable all winter :p
Turns out that you can run ZeoVit stones in one of the chambers in the Elos sumps, it's designed for that type of purpose...hmmm if I make an acrylic bottom plate perfect size and bond a rod to it and make a handle like thing like a coffee plunger....maybe this can work??
