Ok -- This is my 1st post and 1st attempt at a Nano system. Actually been only taking care of a 28,000 gal cement pond (swimming pool-hehe)for the last 8 years. Just discovered the Nano systems recently and now thats all I can think about. I had a 25 gal reef tank back in my college days but always had problems with heat and could not afford a large chiller at that time. I live in Mississippi and it gets real hot in the summer, dont keep the house cold -- only around 78 to 80. Get to hot we go jump in the pool. Im working with my local Pet Store to set up a Nano cube 12g deluxe, my 1st concern is temperature . We are looking into installing an Iceprobe setup with controller. Not real sure if it will fit due to length of probe ??? Anyone have any suggestions, or maybe have done this to a Nano cube-- how well did it work?? Thanks for any comments or suggestions
