sump/refugium/chiller pump location design ha ha ha talk about general

My sump is a bit different from the norm. In the DT I have a well point in there that feeds a Little Giant Pump the line that feeds the chiller has a hole drilled just under the water line to prevent it from draining the tank in case of a leaking pipe. I drilled the whole to break the syphon. That pump feeds the chiller and then the return from the chiller goes back with 1/2 pipe that has 4 return lines hook to it to create flow on the back glass of the tank. The temp probe is in the sump. This is a video of my sump...

I have an HVAC fan on top of the chiller to pull the hot air out of the room. It vents into the attic which I attached to one of the vents from the bathroom so it goes outside through the roof vent. I also put a filter by the air intake of the chiller to combat dust in the coils. Hope this helps.
