DWC cooling with the air pump?

Well been thinking of stuff to do on my first grow. My temps are not to high in the coolers but I was thinking that you could coil up some copper line in a freezer and plumb your air pump with this? I dont know if it would work but its an idea. Also you could run a aquastat in one of the buckets to turn the freezer on and off or just set it at a cert temp..... I would think you would need alot of copper line allmost 100 feet of it.... Just kinda brain storming

I just use a 12gal Igloo Marine cooler w/ 1/2gal frozen water bottles at lights on 12/12.
Temps stay 62F - 64F and less than 69F during lights off.

I have read online where people do that with the copper tubing.

if you have black air line,keep as short as you can and keep it out of the light,I use pipe insulation on mine and it helped
