Substrate Heating - Not!!

[Rodney Dorville/EC/SP_SF <RDORVILL at sp_ac.sg>]

I can see the reason for substrate heating in your parts of the world where 
temperatures are below the 25C mark, however, in the tropics, the coolest your 
water temperature can be is about 27C.   So there comes to mind a number of 
questions:
1.  How do I get water circulation in the gravel?  (a slow powered UGF-perhaps?)
2.  Short of a chiller (which costs a bomb to buy and to run) how can one lower 
the temperature of the water by a couple of degrees?  (the ambient temperature 
is usually 30C).

Thanks,

Rodney in hot and sunny Singapore!
