Hi Baz The chlor powder we have got is called 'hth Choc Poudre'. On the tub it says it dissolves instantly and it can be sprinkled onto to water or put into the skimmers.  We were instructed to sprinkle it all over the surface, not just by the skimmers. I can't remember how much chlor choc tablets cost but this stuff is 19,50 euros for 1.8kg. Bri.

Hi Poppy, Been to one of our pool supply shop this afternoon, with a set of photos, to show what has been happening. Maybe we are lucky, there is an English assistant who speaks perfect French so can liase with the rest of the staff (thanks JJ). The boss decided that we need to get the pH down first by adding 1kg of -pH, mixed with water, every 6 hours until we have used 7 kg.  Assuming the level is then correct, we add a tub (1.8kg) Chlor-choc powder straight into the pool to correct chlorine levels. We'll see! Ian, obviously you enjoyed the football!! Bri.

Hi Poppy, Ok we'll visit one of our pool supplies shops and stock up on Chlor-choc - we have a 11 x 5 pool. What about pH- to lower the pH? Ours is off the scale. Thanks Bri.

Hi Poppy, It's OK saying add loads of Chlor-choc but will (or does) that get rid of the greeny-brown dust that settles on the floor of the pool? Our filter has been running 24/7 for the last month! Bri.

Thanks for that Chas.

The water in our pool - with an abri - was changed completely at the end of January. We also had the sand changed in the filter. The water gradually became green and cloudy. The pH was off the scale and no matter how much -pH we used it never dropped, chlorine level varied. Just over a week since we went to one of our shops in Saintes for advice and were instructed to add flocculant and -pH powder. If we wanted the pool to clear quickly we could use Revatop+ (peroxide). We did all these things and sure enough the water became blue. However the pH still did not drop and we had what appeared to be a greeny-brown ‘powder’ on the floor of the pool. If the ‘powder’ is disturbed the water becomes cloudy. The powder was vacuumed away and the filter backwashed. The day after the ‘powder’ was back, so it was vacuumed away again to waste water and the filter backwashed. The pH is still off the scale, chlorine is nil. The pool was vacuumed again on Sunday and the water is becoming cloudy and green again (with the ‘powder’). Does anyone know of or has used a 'hands-on' (preferably English speaking) expert pool-person around Saintes. We are now getting desperate.
