I’m pretty much done cycling my new 25 gallon lagoon tank but I just learned I need a heater. I did I little research and it seems like 100w is what I need, but I’ve also heard people talk about how they accidentally “cooked “ their fish because the heater malfunctioned. Some say a way to avoid this is getting two smaller/lower powered heaters. Not sure which I should do or what brand of heater is the best, any advice?
