So I have a marineland dual temp heater and I can't figure the darn thing out. The dial, that is. It looks like I can only get it to turn about 35 degrees, from straight up to a little bit to the right. It's overheating my tank and I've tried both ways but it keeps heating. Can someone tell me whether it's straight up or to the right that is 76 degrees?
