After a few weeks the water was very murky brown and I couldn't really see the bottom. I found the product easy to use. I followed carefully the clear instructions for calculating the volume of water in the pond and therefore how much of the product I needed to apply. The water volume calculation could only be an estimate during to the irregular shape and depth of the pond, so if anything I decided to slightly underestimate the amount of product to apply. I mixed it with warm water in a bucket and decanted the mixture into a watering can fitted with a rose, then poured the mixture evenly over the pond surface. The water cleared gradually day by day until after a week it was as clear as could be expected. Now I can see everything at the bottom of the pond, so the product has been very effective, even during extremely hot weather. There is plenty left for any further dosage so I think it's good value for money . Review: Good stuff 👍 - Use this most of the time along with barley straw in my pound works well. I also use in my aquarium but have to get the right dosage exactly or will kill fish, find its much better to use than most of the proper aquarium cleaners which are no good and way over priced will cloud up but that shows it's working within 24hrs water is really really clean when you empty filters use will see results for yourself but as said Got to get dosage right, I have a 200lt best if you know your literage in tank then you get the dosage right, if not have to do by size and that is harder to work out i did get it wrong at first now I don't and a bottle last a long time than others. ## Features - Causes serious eye irritation. - Causes skin irritation. - Contains benzisothiazolone.

Is put half in one bucket and spread over the pond and then wait for an hour to let the first bucket circulate then do the second half of the solution as this seems to work better many thanks gary **Q: Will this work for a small pond with no pump or filtration system?** A: My pond is small, under 200 gallons. I only have a small capacity £15 pump. No doubt the Clear Pond works so much better with a pump to help even distribution of the mixture BUT if you mix the correct amount thoroughly in a couple of gallons of water, then spread evenly with a rose attached to your watering can, then I see no reason for it not to work after a fashion but a pump is certainly a preferable addition even if like mine. My pond is nice ands clear after 8 weeks but it is early days yet. I have not added fish yet and I do have the pump on for 2-3 hours a day and I have a good amount of oxygenator plants which must help. Good luck.DBS **Q: Can i leave my fish in pond while i use pond clear** A: One word...Yes...its a fantastic product. **Q: Anyone know if this can also be used in a small indoor cold water fishtank?** A: Not sure about that. It clearly says Pond and to reduce levels for a small indoor tank could be difficult. Wouldn’t it be better to empty water, clean tank and put in fresh. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked Perfectly for Me *by P***T on 29 May 2026* I have a new wildlife pond that does not have any kind of pump or filter.

The dose was easy to calculate and I sprinkled the solution over the pond surface using a watering can. Left it overnight and the pond water is so clear I can see right to the bottom now. --- ## 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.hr/products/48209554-blagdon-clear-pond-water-treatment-1-litre-clears-dirty-green](https://www.desertcart.hr/products/48209554-blagdon-clear-pond-water-treatment-1-litre-clears-dirty-green) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-28*
