good afternoon everyone, I have been noticing these days that my heater is not working at all well and I put one in the meantime to solve it, but I would like to do something well done and I have read here that heaters can fail and for that reason several people prefer put 2 that go at half capacity instead of one and with an inkbird controller, the tank is a biocube 32 g, can someone give me some recommendations on what to use, I'm new with the tank and the hobby, a friend of mine gave it to me with everything and I want to improve it so that it doesn't go away to fail, thank you
