Review: Effective! - We have a 10ft Bestway max steel pro pool. A little visitor recently asked why the pool was green. Good question. Wed been using one of those little floating chlorine dispensers with the tablets, but after a little tea search, it appeared this stuff was effective in dealing with the algae. And it is! Annoyingly, I didn’t take before and after pictures, but I measured out 60g (a tiny fraction of the amount in the box, making the >£50 price decent value) mixed it in a measuring jug and fired it into the pool next to the inlet pipe. I did that in the evening and by the next morning the pool was clear. I was both surprised and delighted. So we’ll be using this once a week from here on in. Note - we also bought a pool vacuum (to address the detritus on the bottom) but haven’t used that yet.
Review: Quite amazing - I have a 4000L pool and over the last two weeks struggled with greenish water. I had put more chlorine tablets, added liquid algaecide and vacuumed a few times, but achieved little and the water remained cloudy and green. I diluted 80 grs of these granules in a jar and poured it by the outlet. Within SECONDS the areas next to the inlet and outlet had turned clear ! After 3 hours the whole pool is a nice clear blue colour. Not a trace of greenish stuff, I don't even need to vacuum the floor and walls. The water looks like it did the very first day. Brilliant stuff which will last for ages.

## Questions & Answers

**Q: The instructions on the container are only in French. How much do I need to use to shock a 6,473 litre above ground pool?**
A: The label on the front of the tub peels off open it up and its in english . I have a hot tub is that the same as yours

**Q: what size tablets are in these tubs please?**
A: They are granules not tablets, you just sprinkle them in.

**Q: Hi, I have a 3mx2mx1m pool that has a nasty algae problem, 'tis rather green and uninviting, how much do I use to Shock it into deliciousness again?**
A: Dear Ryddie

On the back of the container, you will find a multi-page instruction booklet with the dosing instruction.  This would depend on current levels within the pool, please feel free to call us on 01483 608401 otherwise start with 2 cups full and then test the chlorine levels within the pool after 20 minutes. Your should see the green algae start to turn white and potentially the water turn cloudy from dead algae. 

Regards
Desjoyaux Pools.

A: Good moring, is a chlorine shock treatment containing sodium dihydrate.

I would have given it a 5 star but there are not dosage instructions. Or to be fair, there are very unclear dosage instructions in French.
