Description
Power your large aquarium systems with confidence using the Finnex THD-700S Compact Titanium Heating Element. Engineered for substantial water volumes, this 700-watt heating tube offers a high-performance alternative to traditional glass heaters, combining the superior durability of titanium with a sleek, efficient design.
Designed to handle aquariums up to 200 gallons, the THD-700S maintains a relatively slim 0.74" diameter profile compared to other high-wattage options. This allows it to slide into sumps and filtration chambers where space is at a premium, without sacrificing the raw heating power needed for large reef or freshwater displays.
⚠️ Important: This is a heating element only. A separate temperature controller (sold separately) is required for operation.

Detailed Description
Built for Large Systems The THD-700S is the workhorse of the THD line, rated for aquariums between 110 and 200 gallons. Its robust titanium body is virtually unbreakable, capable of withstanding the rigors of maintenance and heavy water flow that often damage fragile glass heaters.
Engineered for Safety Every heater comes pre-installed with a protective guard. This barrier is critical for the safety of your tank's inhabitants—especially in large tanks with active fish—preventing accidental burns while ensuring heat is dispersed evenly throughout the water column.
Precision Stability When connected to a quality controller, the THD-700S provides the thermal stability large ecosystems demand. Its internal quartz sleeve promotes consistent heat output, helping to eliminate temperature fluctuations that can stress sensitive marine life and tropical fish.
