Already got it covered.
I made a DIY two stage canister filter that uses 2" pvc
as the canisters and is about 30" tall. The whole canister assembly will fit nicely into a tall trash can like the size you would use in the kitchen, and then I can fill the can up with ice when it gets too hot.
Haven't tried it yet, but I think with a little improvisation I could get it to keep the temps under control......with supervision.
