Need help with my chiller

[rhysolotl]

Hi! I have a Hailea HC 300A chiller for my tank. It has an IN and OUT hose on it. I have a pump and return hose (u bend) in my tank. Which of these should I connect to the IN and which connects to the OUT?

Hi!
I may be misunderstanding, but I would assume the return hose (where you want the water to go back into the aquarium) connects to the OUT, and the pump (which takes the water from the aquarium) to the IN. Right?
