Review: Brilliant! Worked overnight - Does exactly what it says! I had been in an endless cycle of shocking the pool, upping the PH and adding clarifier and getting very little improvement. The liquid clarifier just wasn’t working quick enough. Thought I’d give this a go as fairly inexpensive. Worked out my pool is 20m³ and used 4 scoops sprinkled in front of the jet, I stirred it with the skimmer net handle and immediately could see it form tiny clumps in the water… this was brilliant as knew it was working. Left the filter (sand filter) running when I checked on it in the morning just 10hrs later, I could see the bottom of the pool. It was crystal clear compared to the chalky white of the day before. There was a sludge of dirt in the centre, I just vacuumed this up, then back washed the filter, had to stop and add more water to the pool so could backwash again until the backwash water ran clear. 3Hrs later had a tiny bit more to vac up and tested water and all levels were good and pool ready to use! Wish I tried this first as so much better than clarifier and the tub will last all summer. So glad I got this floc! Review: What a difference a day makes - I purchased this despite bad reviews because I was in a hurry with visitors coming to stay. Following instructions I applied it early in the morning and left it to settle. I was very disappointed and angry that evening when it appeared worse than ever with little flakes adding to the cloudiness of the water. Accordingly I switched on the filtration system again and started composing a very critical review. However, on removing the pool cover the following morning I found the water to be crystal clear and perfect for our guests! What a relief. ## Features - ✅ Fast Water Clarity – Concentrated natural flocculant that clears cloudy pool and spa water in just a few hours.

However, it is not a disinfectant, so it should be used as a complement to water treatment. **Q: Can it be used with filtration systems that use filter balls?** A: Yes, the product is compatible with filter ball systems, but it's always recommended to check the filtration system manufacturer's instructions. **Q: Does it help with cloudy or slightly white water at the bottom of the pool?** A: Yes, it is formulated to clump suspended particles and facilitate their removal through filtration or vacuuming. It is useful when the water is slightly cloudy or has fine residue **Q: Is it suitable for hard water that leaves white residue at the bottom?** A: It can help, but if the white residue is due to limescale precipitation, the flocculant alone is not enough. In such cases, it's also recommended to use an anti-limescale product or a pH reducer if levels are high. **Q: Does it serve as a disinfectant for pools?** A: No. Its function is to clump and precipitate suspended particles. Disinfection must be done with chlorine, bromine, or another compatible disinfectant. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant! Worked overnight *by H***E on 17 July 2022* Does exactly what it says!
