Hello
I have been testing overnight for any loss of Chlorine. Yesterday lunchtime I added Bleach to the recommended level as shown in the Pool Calculator and tested just before dark, the sun had gone down, the test showed the target level of 12ppm had been reached. This morning at daybreak I tested again and got some strange results. Firstly after adding the 0870 powder the water in the tube remained clear, I thought this odd so dumped that and used the fast test method using the blue plastic CH & pH kit and got a very high colour reading. I tried another FC test again this time I got a colour change in the water albeit very faint. I tried again and got a positive change in the sample and a reading of 12ppm. My concern is the 'heaped' amount of the 0870. The shovel is so small what does 'heaped' mean, It is very difficult to judge an exact amount or does it matter? I have noted the more 0870 added to the water sample makes it colour a lot stronger
My test kit is nearly three years old so it maybe too old to use, if so do I need to replace everything? Is there a stockist in Thailand where I can replenish it as postage from the States is very expensive even for small package weights.
Thanks
Mike
