You do not want aluminum in contact with saltwater.
Titanium is usually used.

what is the specific reason for not aluminum corrosion?

Aluminum will corrode in SW. Adafruit has some peltiers with built in heat sinks

Glass is a fair conductor of heat, might be simpler and more efficient to mount the cold side of the Peltier element directly to the tank. I like the idea of a solid state cooler but if evaporation is not an issue (if you have an ATO), I suspect a fan will do more cooling with less energy input.

You could build a heat exchanger.
With this in an isolated tank and run silicone tubing through the cooler water? Slowly might do the trick
