Hi, I am by no means an expert. But I would recommend a drop in chiller instead of the conventional aquarium chiller. The key considerations for drop in is due to size of your tank, a normal chiller will take some time to cool your tank. Add on sound (depending on chiller model) and heat given off by chiller, the chiller placement is also important as you do not want the heat of the chiller to affect your tank. I am sure fellow reefers would be able to give contacts for drop in chiller installation and I see commonly Derrick being recommended. Cheers Sent from my SM-G998B using Tapatalk
