I hear good thing about inkbirds here for having 2 heaters - one as a backup in case of failure. Then I go on BRS and there are quite a few bad reviews. Are these things worth it? Is there one controller that I should be buying over another?
Also, I have a 40b with 20l sump. Will 2 100 watt eheim Jagers be good? Should I do 2 150 Jagers instead of 100?
