ok so i live in southern cali.. always wanted to keep trout and now im gonna try it. im using one of my 100 gallon tanks to test it for a while. im usuing 2 ac110s and an xp3 for filtration. also 3 powerheads 2 of wich will be hooked up to bubblers. i have a mini fridge that ill be running the 3rd powerhead through. 1 question im pondering is could i just use rubber hose coiled up in the fridge? i dont see the absolue need to use copper tube. if i can cut that cost it would be great. also ive never drilled into a fridge before. im assuming all mechanicals are on the rear and i can drill my lines right into the side without damaging anything? also im going to try n set the water temp between 50-55. anybody with input would be awsome. ill take pics of everthing. also how do i transport the trout? im not setting up a chiller to my cooler. just using 2 bubblers. thanks guys
