Algaway 5.4 & Concentrated Barley Straw Extract Pond Treatment - Clear

Our review of this two-pack pond treatment combines an EPA-registered algaecide with a concentrated barley straw extract to deliver clearer water and a healthier pond environment. For pond owners who want a noninvasive way to control string algae and green water while keeping fish and most plants safe, this combo is focused and practical. The biggest reason to buy is the pair of complementary approaches: Algaway 5.4 acts quickly to control visible algae, while the barley straw extract helps maintain balance over time without leaving residue in waterfalls or bottom drains.

Key Features

• EPA-registered Algaecide: Algaway 5.4 targets string algae and suspended algae blooms to restore visibility and reduce nuisance growth in ornamental ponds.
• Safe for Fish and Plants: Both products are formulated to be safe for koi and goldfish and many pond plants when used as directed, allowing enjoyment of aquatic life.
• Fast-acting Barley Extract: The concentrated barley straw extract begins releasing decomposition by-products on contact to support clearer water without a bulky straw bale.
• No Residue in Features: The liquid barley extract leaves no debris to clog bottom drains or mar waterfall features, keeping filtration and circulation clear.
• Convenient Packaging: Tip-and-pour containers and a concentrated formula make measuring and application straightforward for a range of pond sizes.
• Aeration Guidance: The product notes stress continuous aeration via waterfall or fountain to protect fish when treating algae, which helps users avoid fish loss.

Who It's For

This combination is best for owners of self-contained ornamental ponds and water gardens who want to reduce green water and visible string algae without mechanical removal. It is particularly useful where bottom drains, filters, or decorative waterfalls are present and a residue-free solution is preferred.

Those who keep crustaceans such as snails or shrimp, or who maintain sensitive invertebrates, should look elsewhere because Algaway 5.4 is not recommended for use with mollusks or crustaceans. Also, ponds with poor aeration must be equipped with continuous aeration before treatment to protect fish.
