JBL CombiBloc for CristalProfi e1500

This JBL CombiBloc is a genuine replacement foam block for the CristalProfi e1500 external filter. Over time filter foam compacts and loses its structure, and a fresh CombiBloc restores both mechanical filtration of dirt particles and the surface area that beneficial bacteria need.

Key features of the JBL CombiBloc for CristalProfi e1500

• Genuine JBL replacement foam for the CristalProfi e1500
• Traps dirt particles for mechanical filtration
• Provides surface area for beneficial bacteria
• Shaped to fit the filter basket

Replacing foam without upsets

Check the model number on your filter’s label before ordering, as this block is cut for the CristalProfi e1500 basket. When replacing foam, change only part of the media at a time and leave older blocks or other media in place, so enough beneficial bacteria remain to keep the water stable. Note the date of each change on the filter or in a logbook so you know which block is due next. During routine cleaning, squeeze the block gently a few times in a bucket of tank water rather than scrubbing it, which helps it keep its structure for longer.

Good to know

When cleaning, rinse the foam in tank water rather than tap water so the bacteria colony survives, and replace it once it no longer returns to shape.
