I don't remember who posted it or under where. But somebody posted freezing rodi water to stick in tanks to help cool them off. Just wanted to say thank you. My **** AC decide it wanted to go on strike and that is how i keep both my tanks cool. Ac and fans. Well my nano got up to almost 90 degrees & my 125 to 83ish degrees. Well i had pre frozen some in plastic cups ready to go. And plopped them in when i got home and realized it. Temps are in normal ranges and I'm freezing a lot more rodi. Cause ac is still knocked out. So thanks again whom ever it was.
