Review on 🐠 BKTC Submersible Fish Tank Heater 50W - Adjustable Temperature for 5 to 15 Gallon Aquariums by Mindy Hicks

I wish the low and high indicators on the top handle were better. However, you only look at the display in the glass tube, but maybe you need a flashlight for an unlit tank? You may have to rotate it to see that red indicator. Although the start is good. I only see the C scale, not the F, so just convert to US units. Works great, really better than expected, just hope it lasts. Many overpriced heaters burned out just as quickly as cheap ones. You are tired of paying a lot of money for something special, so try cheaper heaters now.
