Oase BioMaster Prefilter Upgrade KitThe Biomaster upgrade kit can be retrofitted to any model Biomaster filter. Kits are available for all sizes, and can be used on both Thermo and non thermo versions of the filter. A newly designed tube inside the prefilter ensures flow rate is maintained for longer, thereby extending the period between cleans of the prefilter foams. Used in conjunction with the new 10ppi foams, this serves to provide adequate prefilter protection for the main filter
