OASE Hel-X 13 Biomedia for BioMaster Filters in Singapore

This 25 litre allotment of Hel-X 13 is the moving-bed style biomedia designed to slot into the OASE BioMaster 250, 350 and 600 canisters. The value of high-surface-area media like this is most obvious in our climate: at a steady 27-29C, beneficial bacteria stay metabolically active year-round, so a well-colonised bed processes ammonia and nitrite quickly and keeps a busy community or messy-eater tank stable between water changes. More effective surface area means more headroom before your bioload outpaces your filter.

Treat this biomedia as your living engine, not a consumable. Only replace it during a full tank restart, since swapping it out otherwise discards the bacteria colony you spent weeks growing and risks a mini-cycle. When you rinse during servicing, use old tank water rather than chlorinated or chloraminated tap, which would kill the very bacteria you want to keep. Stable biology is what lets local keepers run heavier stockings safely.
