Ok no one knows here so will have to rely on google

You need to test the water with a basic test kit that you can buy in pool shop or online for about Baht 200.00

Your pH must be between 7.2 and 7.6

If it is below, you need pH PLUS (soda ash). if it is above, you need pH MInus (dry acid). get these products in (most) pool shops but also certainly online at a GOOD online pool store - shop around and don't be influenced by claims of 'lguranteed owest prices' - the service you get is more important, and check the shipping costs.

Shock the water first with a small amount of chlorine powder, say about 250 gr, and repeat dcaily until the level is correct. After that, for this small pool you can use qa folating chlorine dispenser loaded with chlorine tablets (go for a good quality such as PoolChlor, rather than Acuchlor).

Thanks chaichara

Have been doing some research & came across an article that indicates you go in alphabetical order when dealing with chemical treatments

Also shock treatment is 7 x the daily dose would doing this every day until (as mentioned ) be a lot of chlorine

Take into account this is my first serious effort of owning a pool

I get my products from Aussie

& will be using 5 in 1 tablets
