Fish Tank & Aquarium Heaters

About

Aquarium Heaters From AllPondSolutions Most aquarium fish come from warm waters and need to be above room temperature. Aquarium fish heaters are inexpensive and keep temperatures stable in your fish tank aquarium no matter what it's like outside - vital since fish don't produce their own body heat. AllPondSolutions have their own range of fish tank water heaters plus a new range of Aquarium digital heaters. .aps-buying-guide{margin-top:1.25em;padding:0.9em 1.1em;border:1px solid rgba(0,0,0,0.15);border-radius:8px;background:rgba(0,0,0,0.02);}.aps-buying-guide summary{cursor:pointer;font-weight:600;}.aps-buying-guide[open] summary{margin-bottom:0.6em;} Buying guide Choosing the right heater comes down to matching its wattage to your tank's size - too weak and it will struggle to maintain temperature in colder months, too powerful and you risk overheating during warmer spells. As a general rule, allow around 1 watt per litre for a room kept at normal household temperature, though unheated rooms or larger tanks may need more. If you're unsure how many litres your setup holds, our fish tank volume calculator makes it easy to work out the right size before you buy. Once fitted, a good heater runs quietly in the background, keeping conditions stable for your fish so they can thrive without the stress of fluctuating temperatures - giving you one less thing to worry about day to day.
