I'm looking into 50 watt heaters for my ten gallon tropical setup. Is the Aqueon submersible heater a good choice? It seems to have a lot of mixed reviews (as do most heaters). I'm worried about it malfunctioning or the glass cracking. Any other good options like Eheim?
Well, I’m not fully experienced, only been in this hobby for 3 years. But I have had issues with other heaters not maintaining a consistent temp & then one of the heaters actually overheated & killed my poor betta. After that I went to my LFS & asked them what they had in all their tanks & the answer was Eheims. They are a bit more $ but IMO worth it. It’s been a year now with them & no issues. The nice thing about them is you can calibrate them also.
