HITOP Mini Submersible Aquarium ... vs Aqueon Preset Heater

Since installation, my fish seem way more active than before they were mostly stationary. Temperature also shows me the current tank temperature periodically.

The temperature is super easy to set up and it automatically adjusts to keep the water at the temperature you set. It is easy to setup and works great. The external control of the temperature is very nice, but i would have preferred the controller to ...  Read More

This heater has a built-in thermostat. It's easy to set or change the temp if needed. I still keep a thermometer in my tank to monitor actual temp.

Since they're so cheap, i keep a few spares as backups. The compact size is great! The power cord is plenty long enough as well. Just plug and play, no mess and no worries.

The water temp never strays too far away from the goal temp of 78-80f. The preset temp is a plus! It is preset and is accurate. Temp holds between 76-78 degrees per a zacro digital thermometer.

Small, yet strong enough for up to a 20 gallon aquarium. My formula for heaters is usually 5-7 watts per gallon of water, so for my tank, i would usually go with a 200 watt heater.

Water temperate is consistently around 78 degrees f, where my platies and angelfish like it. The temp on this cannot be adjusted, but maintains an ideal temp for tropical aquariums.

After the first day it's never reached a heated temp at all. This is supposedly preset to maintain 78 degrees yet constantly keeps it at 75 degrees.
