Thanks for that Dave - I'll go to the shop nad ask for some liquid chlorine if the problem persists. There is so much new info for a newbie like me - so thanks to anyone for the replies! I think we're going to end up going for a salt chlorinator for the lower chlorine levels and less handling of actual chlorine.

cyanuric acid - that's the stabilizer right? I've asked at the local pool shop if they sell chlorine tablets without stabilizer and they don't (I think - my Spanish sucks! : ) I took another reading this morning, chlorine seems to be dropping now, looks more like 5ppm, I'll try to source some chlorine without the stabilizer though. Thanks for the baking soda tip, I'll try that. The pool is tiled, and there is no heater - algaecide, we use it, but not sure if it is copper based. - Actually thinking of switching to salt chlorinator or oxyegen or ionising system, do you or anyone else reading this have any opinions on this? - really want to go for an option which is best for the kids and low maintenance for me.

Thanks for the replies. My readings this morning are: pH 6.8 ppm Free Chlorine 10 (the final color on the test strip) - doesn't seem to be going down after shocking about 48 hours ago. ppm Total Alkalinity 80 ppm Stabilizer 150-300 ppm - hard to tell from the test strip - I suppose I could drain part of the pool and top up with fresh water and maybe add some pH+ liquid - Or would you not touch the pH in this case and just wait for it to rise naturally? The granualar chlorine used is trichlor I don't have any other readings.

Hi, This is my first post here... We've had a pool for about 5 years, and I have recently taken over the maintenance of the pool after a couple of problems with your pool company (leaving the pump on rinse and draining about a quarter of our pool for example!) Anyway... After adding back the lost water it took our chlorine levels down to very negligible levels, so I decided to shock the pool - it was generally in good shape - the Ph is a little low and there is a lot of stablizer, and normal alkaline levels (according to the aquacheck test strips). ... So after adding roughly a kilo of granular chlorine directly to the pool (100 cubic metres) chlorine levels now appear to be 10ppm - is this a safe level to enter the pool for adults or small children? Any idea how long it will take for the chlorine to dissipate to normal levels? The pump was opne for about 24 hours after shocking. Thanks in advance - I'm sure I'll have a lot more questions in the future! Richard
