Cold Water Reef Plan

[fishmaster]

A 1/4 horse chiller shoud have enough pull down for that tank. Don't forget to factor in your sump as well. For the extra money a 1/3 might be a better choice as you can use it on a much bigger tank if you decide to go bigger down the road. Also, make sure the one you buy has a thermostat that goes low enough. Some only go down to 15 degrees. You might want to consider a drop in over a flow through-one less thing to plumb.
