The JBL SymecPad II is designed for aquarium hobbyists who use the JBL CristalProfi e range of external filters and require superior water clarity. These high-quality, precision-cut fleece pads excel at trapping fine mechanical particles that standard foam pads might miss, ensuring crystal-clear water. While they offer excellent filtration performance, they are intended for single-use or very limited re-use, as their ultra-fine structure cannot be completely cleared of debris after heavy saturation.

These are precision-cut specifically for the JBL CristalProfi e range; while they might fit other filters, they are optimized for the JBL basket dimensions.
You can rinse and reuse the pad exactly once. After that, it must be replaced.
The pad should be placed in the final filter basket, usually the bottom-most tray, to act as the last stage of mechanical filtration.
No, these pads are for mechanical filtration. Your existing ceramic or bio-media in the other trays will continue to handle biological processing.
A clogged pad will significantly restrict water flow, which can decrease the overall efficiency of your filter and potentially put strain on the pump.
The SymecPad has become fully saturated with trapped debris; remove it, rinse it once, or replace it if it has already been cleaned once.
Check that the pad is correctly seated in the basket without gaps; ensure you are using the correct size for your specific CristalProfi e model.
To set up your filter, remove the existing fine-pored foam pad from the bottom filter basket and replace it with a single JBL SymecPad II. Ensure the pad sits flat against the edges of the basket to prevent water from flowing around it. When cleaning, you can remove the pad and rinse it thoroughly under a tap or in a bucket of aquarium water; however, the manufacturer specifies that this can only be done once. After the second use, the fine structure becomes too impacted with organic material to function correctly, and the pad must be discarded and replaced with a fresh one to maintain optimal flow rates.
