The SunSun XQP is a practical internal filter designed to maintain good water circulation and mechanical filtration in the aquarium. The series comes in three versions with varying flow rates, allowing you to select the right SunSun XQP filter based on your aquarium's size and required water flow.
The different models internal filters offer flow rates ranging from 500 to 1,500 l/h. This makes the SunSun XQP series suitable for both smaller aquariums requiring a gentler flow and larger aquariums that need a higher flow rate.
How to choose the right SunSun XQP?
- 500 l/h → gentler water flow
- 1,000 l/h → medium to strong water flow
- 1,500 l/h → high water flow
You do not always need to choose the highest flow rate. The right SunSun XQP filter depends on the aquarium volume, its inhabitants, and the level of circulation you desire.
In aquariums with more sedentary fish, an excessively strong flow might be undesirable. Conversely, in other cases, a higher flow rate can be advantageous by ensuring more vigorous circulation.

Maintenance
To maintain optimal water flow, the filter requires periodic cleaning.
Cleaning frequency depends on the aquarium's bioload, the amount of waste produced, and the level of debris accumulation in the filter media.
If you notice a drop in flow rate compared to normal operation, it is recommended to check the filter media and intake ports for accumulated debris.
When cleaning, follow procedures suitable for aquarium equipment and avoid using harsh cleaning agents that could contaminate the water.
Frequently Asked Questions
Which SunSun XQP model should I choose?
The choice depends primarily on the required water flow. The XQP-500 offers the most moderate flow rate, the XQP-1000 provides a medium-to-high flow rate, and the XQP-1500 is designed for situations requiring higher water flow.

Yes. The series comes in three different flow rates, allowing you to choose the right model based on the aquarium size and the required water circulation.
Can I use the XQP-1500 in a small aquarium?
It is possible, but you need to consider the water flow strength in relation to the aquarium's inhabitants and specific setup. A higher flow rate does not always mean the filter is the most suitable choice.
