Will this keep the indoor temperature of 10 gallon aquarium cooled to 75 degrees?** A: The Inkbird does not cool or heat anything....it is only a control to turn on a cooling or heating system. it is just the on-off switch for other equipment. I have mine connected to a fan for cooling and an aquarium heater for heat. It work very good...holds my aquarium at 78 plus or minus 1 degree. I have a small 5" fan that cools down my 150 gal tank and a 300 watt heater to warm it up. The heater hardly ever turns on down here, Florida. **Q: Do they make the aquarium + Wi-Fi model/version?** A: We recommend you use C929A WiFi https://www.amazon.com/dp/B07Y2L95KH **Q: When my big pump kicks on, it seems to not be capable of enough amps and it instantly turns off, over and over. Advice?** A: Might need a larger gauge wire ran to it. **Q: So is this thermometer supposed to be calibrated out of the box? I put it in my aquarium and change to fahrenheit and its off by 10 degrees lower.** A: Please calibrate the difference with the actual temperature outside the water tank. Please contact us in Amazon, if the device still read in a big difference. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable and Accurate Temperature Controller *by on Reviewed in the United States July 29, 2026* The Inkbird ITC-308S has been an excellent addition to my aquarium setup.

This particular controller has both a heating and cooling outlet, although I haven’t connected or needed a fan for cooling yet due to the weather.My reef is about 50 gallons total display and sump. It’s a basic sump with only 3 compartments. I have the controller's probe in the middle chamber with the refugium, controlling a 200w Eheim heater in the next chamber with the return pump. I have my heater set at 78 degrees and the controller set to turn on at 76 and shut off at 79. This gives me one layer of redundancy by causing the heater's power get cut if it gets stuck in the on position at 79 degrees. Eventually when the weather gets hot I'm going to set up a fan to kick on if it his 79 degrees.The inkbird was very accurate out of the box, tested with 3 different thermometers. It gives me the peace of mind to know that if the heater gets stuck in the on position, it won’t overheat the tank, and that if it gets too cold or hot, the alarm on the inkbird will let me know. The probe is replaceable so that’s a bonus knowing I can replace it if it fails. It is also an upgraded coated probe that makes it more durable especially in salt water aquariums.I have since gotten a second unit to install on my 10 gallon AIO for more protection from temperature swings, as a lot can go wrong faster in with the smaller volume. The reefing hobby is pretty expensive and no matter how much money you spend on a heater, they will eventually break. Why trust you heater to protect hundreds or even thousands of dollars worth of living things? The Inkbird will not break the bank and is a great alternative to buying an expensive Neptune Apex or something similar.The only improvement that I would love to see is for Inkbird to make a WIFI unit with heating and cooling outlets, duel REPLACEABLE rubberized probes for redundancy, and maybe a dimmable display. Inkbird has multiple versions that have some combination of these features, but not all in one.The inkbird was sent to me for free for review, but it was something I was going to buy regardless. I'm planning on starting a frag tank this year and will get another Inkbird unit for that as well. This product is highly recommended. ## Frequently Bought Together - Inkbird ITC-308S Aquarium Heating and Cooling Dual Stage Temperature Controller Freshwater Saltwater Aquarium Tropical Fish Ornamental Shrimp - J-B Weld WaterWeld, 1 Hour Cure, Epoxy Putty Stick - 2 Pack, Off-White (8277-2) - Pond Armor SKU-CBLUE-QT-R Non-Toxic Pond Shield Epoxy Paint, 1.5-Quart, Competition Blue, 48 Fl Oz (Pack of 1) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/125785026-itc-308s-aquarium-heating-and-cooling-dual-stage-temperature-controller](https://www.desertcart.nz/products/125785026-itc-308s-aquarium-heating-and-cooling-dual-stage-temperature-controller) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-09-03*
