I’d like this as pure as possible if I can get it…
I’ve tried searching to no avail…
I’m pretty sure a Swimming Pool Shop would have some.
Thanks if you can help…
I’m looking for this same information. Did you find anything regarding this? I cannot find a specialty pool store, but I bought Chlorine at First Chemical. They don’t really know anything about shocking however.
Problem with your plants?
Just saw these replies. I never had any luck. Best go on ebay…!
There is a pool supplies shop on Zhongshan North Rd. Opposite and a little bit along from Sogo walking towards TAS. Will check the number next time I walk past. Also not sure what chemicals they have?
