ISO chiller for nano tank.

[Silver]

Looking for a chiller for my 20(ish) enclosed nano tank in Greater Van or lower mainland.
Something that won't break the bank or get "one of those" looks from my husband. I am struggling to keep the tank below 85. (Fans on constantly, LED lights turned too low for my corals or off completely)

He's the one with the big display, I'm just starting out still learning so I'm not sure specifically what I want.
Perhaps thermoelectric. I don't mind drilling the top but I can't drill the tank.

Advice always welcome as well.
