Check out the Marina C10 Submersible on Amazon for $10.00. **Q: Description says "the ht30 is adjustable between 72 degrees f and 85 degrees f". ok, why does the one i received say not adjustable, preset at 78?** A: All of the HT Heaters are preset now. Unfortunately, this is an old image and old description of the former HT 55. The description seems to have been translated to the HT 100 as well. Tetra is working to correct these issues immediately. We appreciate your bringing it to our attention. If you need any other assistance, please contact the Tetra Consumer Relations Team at 1-800-526-0650. **Q: Will this be okay in a 3 gallon betta bowl i'm making? if not any recomendations?** A: Yea i think so. I seriously look at this every day and im sooooooooooo glad i bought it. My betta looked so depressed before in his bowl because my house gets down to 60 degrees and his water was getting cold and now he is so happy his water stays 78 and he swims like a happy fish and has a lot of bubbles on top (means there happy). Its so crazy that warmer* water can make a fish soooo happy. This is a must. Yes buy it for a 3 gallon tank- i think it will work just fine and your fish will LOVE IT i promise! Let me know how it works out for you- because im so glad i got it! **Q: Does it turns off automatically** A: When it reaches the right temp. it automatically shuts off. When the light on it is green, it's heating; when the light is red, it's off ## Frequently Bought Together - Tetra HT Submersible Aquarium Heater With Electronic Thermostat, 50-Watt, 2-10 Gallon - PAIZOO Fish Tank Digital Thermometer Accurate LED Display to Β±0.9Β°F Tank Thermometer Aquarium Temperature Measurement Suitable for Fish, Axolotl, Turtle or Aquatic - Tetra Water Cleaner Gravel Siphon for Aquariums, Easily Clean Freshwater Aquariums --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/258020686-ht-submersible-aquarium-heater](https://www.desertcart.no/products/258020686-ht-submersible-aquarium-heater) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-27*
