The more I look into it I think I'm gonna go with a herby. But now the quesion is gonna be how big of a hole do I need to drill. From the link he had a 3/4 drain line and a 3/4 overflow? What size hole then do I need? What size hole line do I need for the return? That was a very clean setup and I think I might copy that one.
Do I then match the pump to the main drain? or does it really matter? Lots of newb type question I know. Where do I get the bit for drilling the tank (anywhere local in Calgary?)
Thanks
