Tetra Submersible Heaters 50 watt; 5-3/4"; up to 10 gallons
Just what the Doctors ordered/shipped
Excellent choice for my 10 gallon QT/fry tanks. Let it acclimate to the water temp, plug it in, and walk away. Simple, economical, reliable!!!

works well within its limits.
these heaters are awesome so long as you use it within its limits? 100W for a 30 gallon is a stretch. 20 gallon absolutely. but i live in the cold northeast so i always go with a larger heater. i use these in sumps as backups to main heaters, and for the price i also use for emergency heaters. i always have 2 on hand. will hold temperature(when coupled 2 together) in my 180 gallon tanks till i can get to store for replacements. .have them in my kitchen betta tank on up to a 40 gallon feeder tank. economical, automatic, submersible, small... in a word AWESOME...

I have purchased several of these heaters for various tanks, and I highly recommend them. The fact that they are submersible is great. The constant temperature is completely hands-free and accurate. The red and green indicator lights reassure that the unit is working. A solidly reliable heating unit. You won't be disappointed.
