You can chill the tank with a "radiator" instead. The "old way" was to run a
slow flow through some tubing, wrapping the tubing with moist towelling and
directing a fan across the wet towels. Evaporative cooling kept the tubing
chilled, returning cooler water to the tank.

A less elaborate adaptation, but no less effective, is to replace your
background temporarily with dark canvas. If you use no background, simply
attach the canvas so that it hangs against the glass, in contact with it.
Kept damp, the canvas may cool the tank sufficiently without a breeze, but
on those really hot days you can blow a small fan against the *outside* of
the tank and not experience either the outgassing or excessive tank
evaporation that a direct flow would cause.

If anyone's interested, it's the same way the military and a lot of campers
keep drinking water cool - free-hanging in a canvas "listor bag". Works
*quite* well...

In that case, I hereby unofficially say to you:
"Keep up the good work."

Indeed... ;-)
