Just had a look at the pool - the chlorine does seem to have mixed in.
Using the very unscientific test kit (basically it's match the colours) the PH is about 7.2-7.5 and I think the chlorine level is 2-3ppm (which, according to the instructions on the tub, is how it should be). There is no CYA test, so later I'm going to see what test kits are available here and post links to see if you'd recommend them. Strangely, I can't seem to locate bleach with 6% chlorine either - I'll have to research that as well.
At least the pool is usable again now - yay!
