The heater is preset to 78°F and is meant for small tanks holding 3 to 5.5 gallons. Its size suits a fish tank or a fish bowl of that range.\u003c\/p\u003e\u003ch2\u003eWhat comes in the box\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOne 25W small aquarium heater, model G405, in black\u003c\/li\u003e\n\u003cli\u003eOne suction cup for mounting\u003c\/li\u003e\n\u003cli\u003eOne thermometer strip\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow the heater works in the tank\u003c\/h2\u003e\u003cp\u003eThe heater draws 25W and holds a preset temperature of 78°F, so there is no dial to adjust. The manufacturer describes setup as plug and play, with no extra steps before it goes in the water.\u003c\/p\u003e\u003cp\u003eA light on the unit shows what the heater is doing: it turns red while heating and green while resting. The 4.5-inch body sits inside the tank, kept in place with the supplied suction cup.\u003c\/p\u003e\u003ch2\u003eDoes it fit your tank?\u003c\/h2\u003e\u003cp\u003eCheck the water volume first, because the manufacturer gives this heater a range of 3 to 5.5 gallons and it is not intended for tanks outside that range. Measure the space where the heater will sit as well, since it is 4.5 inches long.\u003c\/p\u003e\u003cp\u003eTwo placement rules come with the unit: keep it fully submerged under water before plugging it in, and unplug it and wait at least 10 minutes before tank maintenance or before taking it out of the water. The heater should not be touched while it is powered on.\u003c\/p\u003e\u003ch2\u003eWhat buyers mention\u003c\/h2\u003e\u003cp\u003eSeveral reviewers say the heater fits well in small tanks and a few note that its compact size takes up little room. Temperature stability comes up too, with some reviewers reporting a consistent temperature. A separate group of reviewers mentions that the suction cup comes loose, and a couple describe the setup as plug-and-play.\u003c\/p\u003e\u003ch2\u003eQuestions buyers ask\u003c\/h2\u003e\u003ch3\u003eWhat size tank is this heater for?\u003c\/h3\u003e\u003cp\u003eThe manufacturer gives a range of 3 to 5.5 gallons.

The temperature control receives mixed feedback - while some say it holds at 78 degrees with no problem, others report it takes too long to warm up. The heater's durability and quality also get mixed reviews, with some finding it durable while others report melting issues, and opinions on value are generally positive. The secure fit is a concern, with multiple customers noting it won't stay locked into the suction cup.\u003c\/p\u003e","brand":"AQUANEAT","offers":[{"title":"Default Title","offer_id":44477355884607,"sku":null,"price":28.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/2409\/1199\/files\/aquaneat-aquarium-heater-25w.jpg?v=1794711986","url":"https:\/\/dogjointly.com\/products\/aquaneat-aquarium-heater-25w-preset","provider":"DogJointly","version":"1.0","type":"link"}
