Just a cap full of this product colored my water perfectly for a couple of months! ### ⭐⭐⭐⭐⭐ Pond dye *by E***H on April 2, 2026* Second yr using this and love it. Very easy to use just pour in at my fountain and tbe color is almost instant. Havent had any problems with water for the cows as well ### ⭐⭐⭐⭐⭐ Great way to color pond water *by R***N on November 4, 2025* Works well in my 1 acre rainwater collection pond. Nice color lasts for months or until a heavy rain pushes the blue water over the overflow. I prefer the blue color to the natures brown/green. Adding color to several spots along the shoreline is all you do. Color automatically spreads throughout pond. ## Frequently Bought Together - 1 Gallon 4X Blue Pond Dye - Treats Like 4 Gallons & Covers 4 Acres, Concentrated Pond Dye Blue, Liquid Pond Shade & Blue Dye for Ponds and Lakes, Provides Natural Blue Color, Safe for Fish & Wildlife - Airmax MuckAway, Natural Pond Muck Remover, Cleans & Clears Away Muck & Sludge, Easy to Use Bacteria & Enzyme Tablets, Safe for The Environment, Treats 1,500 Sq Ft, 6 Month Supply, 16 Scoops, 8 lbs - Airmax Ultra Pondweed Defense Aquatic Weed & Plant Killer, Easy Spray Application to Clean & Clear Large Pond & Lake Water, Liquid Treatment Control Concentrate, Fish, Pet & Animal Safe, 1 Gallon --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/623429295-1-gallon-4x-blue-pond-dye-treats-like-4-gallons](https://www.desertcart.hr/products/623429295-1-gallon-4x-blue-pond-dye-treats-like-4-gallons) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-24*
