About This

  • 99% Copper Sulfate Pentahydrate. To be used for large bodies of water, not small decorative ponds, water features, or pools.
  • Controls most species of algae like filamentous, string algae and swimmers itch. Copper Sulfate should be used as a pond algae treatment on actively growing algae in water temperature above 60F.
  • Most effective when cast out on top of thick floating algae mats. Be aware of how much vegetation you are treating at one time. Eliminating too much at once can deplete the oxygen levels too quickly for your fish.
  • Granular Copper Sulfate, 5 lbs
  • DO NOT use in bodies of water that include Koi, Goldfish, Trout, or Grass Carp. These types of fish are sensitive to copper sulfate products.

Review

  • Decorative Garden Lantern Set

    ★★★★★ 5/5 — Rachel S. (Nashville, TN)

    Product: Decorative Garden Lantern Set

    I placed these along our patio walkway and it instantly made everything feel more styled.

    Not overly bright, just a soft glow that looks really intentional.

    Honestly feels like something you’d see at a boutique hotel.

    Super easy to set up too.

    Already thinking about getting a few more for the backyard.

  • Metal Wall Art Outdoor Decor

    ★★★★☆ 4/5 — Marcus D. (Phoenix, AZ)

    Product: Metal Wall Art Outdoor Decor

    This was exactly what my patio wall needed.

    Before it felt kind of empty, now it actually looks finished.

    The design is simple but stands out just enough.

    Only reason for 4 stars is I had to adjust the mounting a bit, but nothing major.

    Overall, really solid piece.

  • Hanging Planter Decor Set

    ★★★★★ 5/5 — Olivia B. (Charleston, SC)

    Product: Hanging Planter Decor Set

    I hung these near my outdoor seating area and it completely changed the vibe.

    It feels more alive and put together now.

    They’re lightweight but don’t feel cheap at all.

    Even my neighbor asked where I got them.

    Perfect if you want that “styled but not overdone” look.

  • Decorative Garden Stakes

    ★★★★☆ 4/5 — Jason M. (Seattle, WA)

    Product: Decorative Garden Stakes (3-Pack)

    These are small, but they make a bigger difference than I expected.

    I added them around a few plants and suddenly the whole garden looks more intentional.

    They held up fine in the rain too.

    Shipping took a bit longer than I hoped, but the product itself is worth it.
