So i set up a 125 gallon not too long ago (transferred thungs my other tanks into this one) and things were fine. Lately though the temperature is above 80....with it reaching 84 on Saturday. I used a fan and some ice cubes in my sump and I got it down to 77. It was steady at 78 until i wake up this morning and its 81.
I have led lights 12"above the water, a glass top (which im sure can trap some heat but am riskng somwthing jumping out) and a rio3100 pump. I think the pump is the culprit.
How so i kee the temp down? I would prefer not using a chiller. Any advice will be greatly aappreciated
