Was worried sick seeing my fish with fin rot due to my neglect. Was sceptical buying it but thought it was worth a try. One week after treatment fin has healed. Does turn the water a nice turquoise colour but eventually returns clear. ### ⭐⭐⭐⭐⭐ Good *by on Reviewed in the United Kingdom 20 June 2026* It works just great ### ⭐⭐⭐⭐ Worked well, but dyes everything *by on Reviewed in the United Kingdom 7 June 2026* Needed to treat my fish after some new additions. It does work well, but turns the water a vivid green colour, and should you have any air lines etc in your pond it will dye them. Remember that this treatment takes several days of adding, so just when the water starts to clear you turn it vivid green again.Fish are now healthy, and as it was on offer it was cheaper than local aquatic stores.It wont do anything to control Algae and please read the full instructions and warning on the bottle as its not suitable for all fish. A good sized bottle will allow me to do a second complete treatment should it be required. ## Frequently Bought Together - Blagdon Extra Strength Concentrated Formula Anti Fungus & Bacteria Water Treatment for Pond Fish, Finrot, Mouthrot, Goldfish, Koi, Carp, 1 Litre - Blagdon Guardian Pond Tonic Salt, for Fish Health, Water Quality, General Tonic, pH Buffer, 2.27kg, treats 2,273 litres - Evolution Aqua Pure Pond Bomb – for Crystal Clear Healthy Water, Treats up to 20,000 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.co.za/products/59819103-blagdon-extra-strength-concentrated-formula-anti-fungus-and-bacteria-water](https://www.desertcart.co.za/products/59819103-blagdon-extra-strength-concentrated-formula-anti-fungus-and-bacteria-water) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-16*
