Designed & manufactured by Atlan StormwaterEvery Atlan island is built from one thing: the 8 sq ft island kit. Pick how much coverage you want, and that's how many kits you order.
A 34" x 34" floating square. $599 with hardware and free shipping. Just add plants.
Nylon bolts join kits edge to edge — rows, rectangles, or organic shapes that hug your shoreline.
Add kits next season without pulling anything out of the water. Start small, expand as you see results.
Engineering note: inside each kit are two triangular HDPE modules that bolt into the square — Atlan's triangle geometry is what lets islands curve around shorelines and flex with waves.
NC State field trials measured 77% phosphorus removal at roughly 1% coverage when islands were positioned at the pond outlet. Strategic placement stretches every square foot: start with a pilot island, place it well — we'll show you where — and expand each season.
Size My Pond Exactly| Pond size | 2-3% habitat tier | 5-10% water-quality tier |
|---|---|---|
| 1,000 sq ft ornamental | 20-30 sq ft = 3-4 kits | 50-100 sq ft = 7-13 kits |
| 1/10 acre (4,356 sq ft) | 87-131 sq ft = 11-17 kits | 218-436 sq ft = 28-55 kits |
| 1/4 acre (10,890 sq ft) | 218-327 sq ft = 28-41 kits | 545-1,089 sq ft = 69-137 kits |
| 1/2 acre (21,780 sq ft) | 436-653 sq ft = 55-82 kits | 1,089-2,178 sq ft = 137-273 kits |
