Installed the foam set in my BioMaster 600 filter and noticed a significant improvement in water clarity. The foam holds up well and fits securely. Easy to replace when worn out.

Works perfectly with my BioMaster Thermo 350. The foam is durable and helps maintain good filtration. Slightly harder to install than expected, but the instructions were clear.
