I'm currently in the process of setting up my new 90 gallon tank and gathering all the necessary components for it. A sturdy titanium heater rather than a glass one was recommended to me so I searched for one and found one on Amazon called the Hygger. It's 500 watts and recommended for 60-120 gallons and you can digitally set the water temperature you want. The thing is it only has 71% 5 star ratings and I guess that's okay but not perfect. I don't always trust negative reviews on amazon because a lot of complaints seem to be by people who don't know how to operate what they bought so does anybody here know about this heater or have experience with it? Is it a decent heater? Is it reliable? I want to keep my tank at a constant 77 degrees and occasionally bring it up to 80 for a couple days to increase the odds of some possible livebearer spawning.
