Because it's black it doesn't need cleaning yet. It's been in 2months. **Q: Can I use this to dye mulch as in wood chips for garden?** A: Yes **Q: would this hide the pump in a small water feature?** A: this stuff is great and very dense in colour (wear gloves). it turns the water jet black. anything submerged will not be seen. add it gradually until you reach the desired depth of colour - a little goes a long way. it also helps to keep the algea at bay. hope that helps **Q: Would this dye stain a white bathtub?** A: don't know ive only used it in glass ## Frequently Bought Together - HYDRA BLACK LIQUID DYE 250ml treats UpTo 1063 litres Concentrated Liquid Pond Dye Free of Pesticides, Algaecides Safe for pets fish plants - Envii Pond Klear Xtra – Strong Pond Clear Water Treatment, Naturally Clears Green Pond Water – Treats Up To 100,000 litres --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/48878579-hydra-black-liquid-dye-250ml-treats-upto-1063-litres-concentrated](https://www.desertcart.tn/products/48878579-hydra-black-liquid-dye-250ml-treats-upto-1063-litres-concentrated) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-03*
