UltraZap biofilter spares keep your pond, aquarium or fish tank biological filter running when a single part fails, instead of replacing the whole unit. The range covers the biofilter lid, the lid o-ring that seals it, and the union nut and flange that connect the filter to your plumbing. A cracked lid or a tired seal is a fix, not a new filter — the biological stage keeps working while you sort it out.

Good to know:
– Biofilter lid only
– Lid o-ring seal
– Union nut and flange
– Fits the standard UltraZap biofilter range
– Sold per part, so you replace only what has failed
