I did up a pair of salted ice blocks, sealed, and set half in half out of the water. I don't know how long they lasted. Sometime tween when I left them and came back 5 hours later. I knew it wouldnt last. First time in the room was all about seeing what I'm working against. The next idea requires tap'n the budget for more hose, and another pump.
Otherwise, the whole thing is right at room temperature -- 78°F / 26°C

One thing I dufus'd in the over all cost...(like duh even) I already had the AC/DC adapter...probably a $10-20 sort of thing.

The reason for converting AC to DC is economy. A 500gph / 1890lph for $10 yank that can be replaced super easy by a walmart run. I doubt anytime in the next 10,000 hours of use to have any issue other than routine flushing and cleaning. Oh yeah...it is also how I'll be draining the solution when time for a water change. A cheapy diverter and a shut off valve will the do the trick. Or maybe even just a cap that can be removed. Ehh.

Hoping to have a chill'd solution tub before the weekend goes bye bye.

I smell a Friday out there somewhere.
