Frequently Asked Questions

Q: Where do I attach the aquarium thermometer strip on my fish tank?

A: Attach the strip to the outside of your glass aquarium, ideally on a flat, clean, dry surface away from direct sunlight. Clean the glass thoroughly before application for the best adhesion. Note that once applied, the strip cannot be removed and reused.

Q: Is this aquarium thermometer strip accurate?

A: Yes — the PET liquid crystal thermometer provides a reliable reading within a degree or so. The color-change system (green = current temp, blue = cooler zone, brown = warmer zone) makes it very easy to judge whether your tank is at, below, or above the displayed temperature.

Q: Does this thermometer work on acrylic tanks as well as glass?

A: This strip thermometer is designed primarily for glass aquariums. Thicker acrylic walls may insulate the strip from the water temperature, potentially affecting accuracy. For best results, use it on standard glass fish tanks.

Q: What temperature range does this aquarium thermometer cover?

A: It covers 18°C to 34°C (64°F to 93°F), which is suitable for most freshwater tropical fish, shrimp tanks, and common aquarium setups.
