Help! My planted tank is hovering around 28.8 to 29C and I can lower it with my Vista Fan (Profantec fan) to around 28C but I can only do it at night. The fan is so freakin' noisy, it drives me nuts if I turn in on during my waking hours. I've already done whatever I could, not to impede airflow, including removing the grill. Seems to reduce the noise somewhat. Heard from some people I should leave my fan on 24-7 if I want a significant drop in temperatures...Oh, BTW, the airstone comes on at the same time the fan comes on (ie. when I go to sleep). Anything else I can do? I'm a doofus when it comes to wiring so I'm not sure how to even step down the electrical energy to the fan... any other practical suggestions?
