chiller question

[olemiss]

What chiller would y'all recommend for a 30 tall. This is my first chiller and I really have no idea about the 1/15, 1/10....
All info appreciated. The tank gets up to 83, dang ole south Louisiana.

look at 1/13 or 1/15 though you can do 1/10 if you ever plan on upgrading.
You are better off buying a little bigger just in case.
