Chiller advice

[May&Bruce]

Hey guys......what size chiller for a 5foot 150 gal tank? Would like to know a scientific way of determining this not just a hit and miss or 'as large as money can buy' answer. I have seen one formula on http://www.jbjlighting.com/prod_chiller_size.asp but the resulting chiller sounds too small.

Any ideas????

Different brands chiller works differently. Artica one might sounds too small hp but their cooling power is good especially for the commerical series.
