Nortembio Concentrated Natural Flocculant, 12 Weeks. Turbidity Remover for Big Pools and Spas. Clarifier Agent for Clear Water. Organic Product Safe for the Whole Family.

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!

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.

Done what instructions said twice and has done nothing! Complete waste of money and so disappointed!

Great ty

This product was a cheap alternative for my pool compared to bestway chlorine shock it’s easy to use just sprinkle on ur pool let the filter do the work but it does not dissolve very well and you go in the pool after a full 24 hours filter to what looks like flakey skin floating around

I was struggling to get my above ground pool properly clear. One application of this and 12 hours later all wonderfully crystal.

Easy to work with if there is no wind! Just sprinkle on the water - it does take some time to break down into the water and therefore longer to clear the entire pool but it does work well.

Very disappointed in this product that made zero difference to my algae problem. Had to look elsewhere for a solution.
