corkman 164 Posted January 15, 2012 Share Posted January 15, 2012 Hi All, Could someone please tell me where I can buy this stuff in Bangkok? Many thanks in advance. Link to post Share on other sites
monty1412 994 Posted January 15, 2012 Share Posted January 15, 2012 Muriatic acid is just hydrocholoric acid so any homepro or like should have it. Just premix with water before you add to pool and remember add acid to water when premixing not water to acid ( dissolution is highly exothermic and if you add water to the acid it can explode back out all over you. Gloves and eyewaer and you are in control cheers Link to post Share on other sites

I'm a little bit ignorant, but I've read Muriatic Acid is about 35% the strength of hydrocholoric acid - so I should use about 1/3rd of the mix? Cheers. Link to post Share on other sites

Muriatic acid and hydrochloric acid are the same . It is just a different name . 35% is near the highest reachable as it is a gas in water solution . Smoking HCL is 37% if i remember correct , and you will see fumes of white smoke going out of the bottle . 35% is just below that , so it is very concentrated stuff .

SantiSuk 3403 Posted March 21 Share Posted March 21 Global House used to have it in 20kg carboys in the two branches within driving distance of me (Ubon Ratchathani and Kantharalak) at about 280 baht, but they both seem not to have restocked in recent months. Haven't yet asked if that is intentional or just a short term supply issue. Prior to Global House, when the largest of the watsadus (DIY sheds) in Ubon had stopped stocking it 8 years ago I could not find carboys elsewhere in the other national chain watsadus or builders merchants locally 'for love nor money'* - despite those pool guys in Bangkok and Pattaya on pool threads annoyingly saying it's available at all builders merchants! My guess is that many retailers find handling such a dangerous chemical a pain in the proverbial! I found myself back then 6-8 years ago having to collect it in bulk (ie 5 or more carboys at a time) from a builders merchant in Roi Et (a friend living there had alerted me to it) or Buriram (well-known watsadu just north of the ring road). Then Global opened locally. Now I'm back to square one and will have to troll round the local watsadus again when I get nearer to running out. *Some had smaller bottles but not at a very economic price. I'm recalling3 litres for 100baht kind of price) Link to post Share on other sites

SwimmingPoolsThailand 102 Posted April 6 Share Posted April 6 To dispel some of the conjecture: Muriatic (American English) and Hydrochloric Acid are exactly the same product. It is used in pools for reducing the pH but it is a very common chemical - it's what your stomach produces to digest your food. Due to the bed rock type in most of Thailand (usually sedimentary rock - limestone), most pools regularly need pHminus or hydrochloric acid to keep the pH down to 7.2 to 7.6. Ask for กรดไฮโดรคลอริก (pronounced as in English ' hydrochloric acid'), or its more common name here กรดเกลือ, pronounced 'grot gloowa', literally 'salt acid' - Salzsaüre as it is known in German. Hydrochloric Acid is widely available at many Mom & Pop hardware stores and in all Home Supplies Centres such as Do Home, Home Hub, Thai Watsadu, and Global House. It is sold in 20 Litre PVC canisters and costs around ฿270. In pools, because it gives off dangerous fumes and is difficult to store, Hydrochloric Acid is only generally used together with automatic pH monitoring and dosing systems. Much safer and easier to use (and goes a lot further for the price) in other pools is pHminus (sodium bisulphate), sometimes marketed as 'pH Down', a 'dry' acid available from all pool stores and online but at wildly different prices - some plainly extortionate. Shop around. Link to post Share on other sites
