When it gets hot in AZ, the best I can lower the wort to using my CFC is about 80-82 F. I then use this pump (https://www.amazon.com/gp/product/B000X05G1A/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&psc=1) along with an ice bucket and CFC to lower the wort temperature even further. The nice thing with this pump it has a 1-1/4-inch NPT discharge with a 3/4-inch garden hose adapter.
