Hey guys, so I've been trying to pick out a heater for a 125g (first tank) but all I've learned so far is that heaters are super finicky. Even the well-known/trusted brands have like 30% bad reviews that say that the heater killed everything in their tank and then burned down a small village lol. I'm also not sure on wattage, the internet says it should be 3-5 watts per gallon, which would mean that my tank needs anywhere from 375w to 625w. Right now I'm thinking either x2 300 watt Aqueon pro series or x2 300 watt Fluval E. I've read that a lot of people like to distribute the work between two heaters. Is this overkill? Does anybody (especially with a bigger tank) have any reliable heaters that they can vouch for?
