I stared at the thermometer upon my 75-gallon Discus tank yesterday. It read 72 degrees. My heart dropped. These fish dependence it hot. Like, tropical-vacation hot. I checked the heater. The vivacious was on. But the water was cold. Why? Because I used a generic "5 watts per gallon" rule. That decide is a lie. Its a leftover of the 90s. We dependence something better. We compulsion precision. That is why I am sharing My suggestion For An Aquarium Heater reef salt calculator on every My Tanks today. Seriously, stop guessing. Your fish are literally swimming in your mistakes.

Most people go to a pet heap and purchase a heater based upon the box. The bin says "for 20-gallon tanks." Thats pointless information. It doesnt account for your house temperature. I alive in a drafty Victorian house. My vivacious room stays at 62 degrees in January. If I desire my tropical fish at 80 degrees, a conventional heater will struggle. It will rule 24/7. next it will burn out. then your fish die. Its a cycle of tragedy. The aquarium water temperature is not just nearly the volume of water. It is very nearly the ambient room temperature beside the target.

I teacher this the hard way. I had a beautiful 10-gallon shrimp tank. I used a preset aquarium heater. I thought I was physical smart. One night, the heater contracted to go rogue.
