no ne .. any ideas anoyne ?

Try Lemon juice.

low cost and you can buy any where

Macro, Tesco, Big, C.

Go to one of the many shops that filter there own water using RO, they should have or be able to help?

Or go to Lam Chabang area and find a ships chandlers, a lot of ships use RO and would need to buy chemicals for maintenance.

You can dissolve Calcium salts with acetic acid ( white vinegar )

I am looking for citric acid powder as well. I looked in several pharmacy, all big supermarket, but I should need any chemical company.

I know where to buy in bkk but not in pattaya yet. I know that lemon juice and vinegar are similar but i need citric acid.

anybody know any chemical company in pattaya?

Any acid will do this. Vinegar will be fine.

Google K&N Thailand Co, Ltd.

They are manufacturing and maintaining R.O. systems outside Pattaya in the NONG PLA LAI area close to highway 36

and have all the chemicals you need to maintain or clean an R.O. system.
