Algae Blaster (Liquid Solution)

BBA PurePond Algae Blaster – Natural String Algae & Blanket Weed Treatment

Struggling with green strands of string algae clinging to your rocks, pumps and pond liner? BBA PurePond Algae Blaster is a natural, Australian-made bacterial treatment that targets filamentous algae (string algae) and blanket weed at the source — without harsh chemicals or copper-based algaecides.

Instead of chemically burning off algae (which can risk overdosing and oxygen crashes), Algae Blaster uses fast-growing, locally selected beneficial bacteria to out-compete algae for the nutrients it needs to grow. As those excess nutrients are consumed, algae is starved back and your pond water returns to clear, balanced and healthy.

This powerful 20x concentrated formula also breaks down organic matter, ammonia, nitrites and phosphates, helping to build a stable microbial ecosystem and reduce ongoing pond maintenance.
