Absolutely safe:
No release of pollutants into the water thanks to neutral foam. Open-pored through dedicated high-pressure treatment.

Quality of foam:
Foams used in aquaristics with live animals must always be subjected to a pollutant test, as most plastics release problematic plasticisers into the water. All the plastics used by JBL have passed this test and do NOT release any harmful substances into the water.

Cleaning of plastics:
For many months it is sufficient to rinse the dirty filter sponges under lukewarm running water and then inoculate them with filter bacteria (JBL FilterStart) before using them again. However, as mechanical cleaning NEVER leads to complete cleaning and dirt will remain in the filter sponge, it is recommended you replace the filter sponges about every 6 months.

Using JBL Coarse Blue Foam in Singapore tanks

We stock this coarse blue foam mat because it earns its place as the first mechanical stage in almost any filter our customers run. Cut a piece to fit your canister tray, sump, or sump-style overflow, and it traps the larger debris before water reaches your bio-media. In Singapore’s warm tanks, where biological loads tick along fast at 27-29C, keeping the coarse stage clean is what keeps your finer wool and ceramic rings from clogging prematurely.

The 50×50 sheet gives you enough material to re-cut replacements over many months, which suits hobbyists juggling several tanks across an HDB or condo setup. Rinse it in old tank water during your water change rather than under the tap, so the cleansing bacteria colonising the foam survive. Because it releases nothing into the water, it pairs safely with shrimp, planted scapes, and sensitive community fish alike, freshwater or marine.
