Happy HolidaysChuck from delawareadamskemp@gmail.com **Q: How often do you need to add new block?** A: First time two blocks but depends on size and every month then after the shock. **Q: Does aeration help when using pond boss block** A: Aeration can be used when using the Pond Boss Block. **Q: Will it clear up muddy water in 1 Acre pond?** A: No. Muddy water is a turbidity issue. Use gypsum or small quantities of alum to clear muddy water. You will also need an aerator. Make sure you use proper quantities when dosing. --- ## 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/10178888-pro-the-block-water-clarifier-sludge-and-odor-remover-5](https://www.desertcart.tn/products/10178888-pro-the-block-water-clarifier-sludge-and-odor-remover-5) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-19*
