Constructed from 2mm thickened quartz glass, this heater is engineered to be explosion-proof and corrosion-resistant. Its thumb-sized frame makes it exceptionally easy to conceal within your aquascaping layout while providing consistent heating power for freshwater and marine tanks up to 26 gallons.

The integrated LED digital display and external controller allow for precise temperature adjustments without needing to submerge your hands. Advanced safety features include dry run and overheating protection, which automatically disable the unit if water levels drop or temperatures exceed 95°F.
