Peter,
I don't think Shawn was suggesting a ban on chillers, however the prophylactic practice of using the chillers to chill the water down to 24-25 degrees when it can run comfortably at 28 degrees.

(I can't get my head around Fahrenheit, sorry, temps in Centigrade).

Obviously chillers need to be utilised to avoid catastrophe, however, people get too hung up on exact numbers.

On Arlington reef on the GBR (where we do a lot of collecting) water temps swing from 29-30 degrees in summer to 22-23 in winter.
Surface temps of 32 are not uncommon either.
Ever been diving and started sweating? Welcome to my world. We need to cool off after 3 hours chasing fish!

EDIT: Diid some conversions for you:
22 C =71.6 F
23 C =73.4 F
24 C =75.2 F
25 C =77.0 F
26 C =78.8 F
27 C =80.6 F
28 C =82.4 F
29 C =84.2 F
30 C =86.0 F
31 C =87.8 F
32 C =89.6 F

FWIW I always have run my tanks around the 81-82 F mark
