## Summary description

sera Termometr Szklany Cienki is a thin glass aquarium thermometer designed for monitoring water temperature. The compact glass stick format provides straightforward temperature reading and can be placed inside the tank or attached to the glass. It is suitable for freshwater and marine aquaria to help maintain stable conditions for fish, plants and invertebrates.

## Long description

sera Termometr Szklany Cienki is a thin glass aquarium thermometer designed to monitor water temperature in both freshwater and marine tanks. The compact glass stick format allows for easy placement either submerged in the water or attached to the inner glass wall. Its clear scale and slim profile make it suitable for small to medium aquaria where unobtrusive, continuous temperature monitoring is required to maintain stable conditions for fish, plants and invertebrates.
Advantages
This glass stick thermometer provides a straightforward analog temperature reading without electronics, ensuring immediate visual feedback. Its slim design minimises visual impact inside the aquarium while allowing accurate placement close to inhabitants. The durable glass construction resists corrosion from aquarium water and the simple format requires no batteries or calibration for routine home use.
Suitable for
Freshwater community and planted aquaria
Marine and reef tanks for general temperature monitoring
Breeding setups and quarantine tanks where consistent temperature is important
Small and compact tanks where space is limited
Key specifications
Design: thin glass stick thermometer for in-tank use or attachment to inner glass
Measurement type: analog temperature display
Compatibility: suitable for freshwater and marine aquaria
Installation: can be submerged or fixed to aquarium glass
Power: passive device — no batteries required
How to use
Place the thermometer in the aquarium where water flow reflects typical tank temperature—near circulation but not directly in front of filter outflow or heater to avoid localized readings. For attachment to the glass, position the stick thermometer on the inner surface at the desired depth and ensure it sits securely. Read the scale at eye level to avoid parallax error and verify the reading after the aquarium has been stable for at least 15–30 minutes. Clean the glass thermometer gently with aquarium-safe materials during routine maintenance to remove deposits that could obscure the scale.
Usage recommendations
Check the thermometer regularly and compare readings with another reliable thermometer if precise control is critical (for example in breeding or reef systems). Avoid sudden temperature shocks to the glass by not exposing it to extreme temperature changes outside the tank, and handle the glass with care to prevent breakage.
