Common Questions

Is this safe for shrimp and other invertebrates?
Invertebrate safety is not verified. The product is described as safe for fish when used as directed, but the seller lists aquariums with invertebrates as not for, and reef keepers needing coral-safe confirmation should avoid it.
What quantity is needed for free shipping, and is a bottle included?
You must order at least 2 bottles for free shipping; each bottle variant is priced at $1.81 USD. Ordering fewer than 2 bottles requires a shipping fee, and if that fee is unpaid the order will not ship. One listed variant is a 300ml Fast-Acting Water Purifier.
Does this work on blue-green algae in a freshwater aquarium and on dinoflagellates in saltwater?
Yes. It is formulated for blue-green algae, dinoflagellates, and filamentous algae, and it reduces bioluminescent bacteria. Use cases include treating blue-green algae on substrate, decor, and glass in freshwater tanks and controlling dinoflagellate slime in saltwater tanks.
Will it harm live plants or my biological filter?
The listing does not specify effects on the nitrogen cycle or filter bacteria. It is used to reduce filamentous algae on live plants and hardscape, and it is described as safe for fish and other aquatic inhabitants when used as directed.
How long does shipping take and are there any restrictions?
The product ships from China; cross-border delivery typically takes 7–30 days depending on the shipping tier, and checkout requires human approval. Free shipping requires a minimum of 2 bottles; otherwise a shipping fee applies and the order may not ship if unpaid.
