I need to know how much my tanks running are costing me so I can tell my wife exactly what they cost lol. I have a 90,75,55,and55. I'm running 3 aqua clear 110, 2 aquaclear 70, one sunsun 304, 2 250 watt aquaeon pro heaters, 2 200 watt aquaeon heaters, 4 small air pumps, 4 aquaeon led 48" lights. I would greatly appreciate the help I can't figure it out. I estimate my water bill on changes at $5 dollars a month.
