ISO chiller for nano tank.

[timmmmy55]

ya you can buy thesew chip on fans for tanks they do work quite well

i put a 4 fan on my brother 40 gallon and it dropped 5f over the first couple hours

done this a few times does work you will just have to top up more often

I have two tiny flat wired fans that should fit into the hood, and point out (and in) through the existing vent grates.

That's out of my scope and hopefully hubby can figure it out! Lol.
