Frequently Asked Questions

Aquarium Heater 50WAquarium Heater 50WAquarium Heater 50W

Q1: Why does the heater have yellow spots or loose quartz?

1. The above phenomena do not affect the use of the heater.
2. The reason for the yellow spots is that the milky white quartz tube of the heater is heated.
3. Quartz is loose due to expansion and contraction by heat.

Q2: Why is the temperature control inaccurate after using the heater for a period of time?

Affected by cold weather, the heater will produce a scale when working in the water for a long time, then the scale attached to the heater will affect the temperature sensing system of the heater and cause the heater temperature to be inaccurate.
Therefore, we have recommended users clean the heater's scale regularly.

Q3: Why is the heater required to be installed vertically where the water flows?

First, the water in each part of the water tank flows through the heater, so that the heater quickly detects the water temperature of the entire water tank and automatically adjusts it to the set temperature.
Second, the water flow continuously impacts the heater, which makes the temperature of the heater diffuse faster, and avoids the heating rod from scalding the fish due to the high temperature.
