I was wondering, I have a DangerDen kit<Largest one> hooked up now with my Eheim 1250 Hobby Pump. I was wondering what kind of decrease in temps I would recieve if I hooked on another radiator. I was thinking of yet, another cooling cube from DangerDen.com and wanted to know if anyone has tested this out. Even if it was with a different setup then I. Thanks ya'll.
