Hi Just an update, I have looked everywhere in upstate South Carolina, and all the stores, Walmart, Lowes, Ace Hardware, BiLo, Publix, Ingles, CVS, Walgreens etc all had surfactant in it. Quick note the one at lowes I bought not realizing surfactant was listed, shook all the bottles on the shelf (about 10 - I must have looked crazy to the other customers) but none of them foamed so I bought it and brought it home that is when I realized it had surfactant in it. Anyway long story short I finally found some at The Dollar Store 2 QT for a buck. It only lists ammonia and does not foam ... Brand is "Austin's Clear Ammonia". I looked it up online and other people have used it with sucess, just note that if you do use this brand it is only a 2-4% ammonia so you will need more to reach the desired ammonia levels in the tank. I will be using it for the first time, new tank arives in 3 days, can't wait . I will let you know how it goes.
I've been having problems finding Ammonia for ages, went into loads of Boots, big and small and none had any, I asked too and they said "We don't stock it any more", mmmm, "any more", strange. Homebase and other DIY places etc had none.
I went onto Boots website, they have it there for £1.75 for 500ml. Postage is £2.90 though.
BUT... if your local store doesn't have it, and you don't want to pay the postage, you can have it delivered to your local store for FREE!
Boots, B&Q, Homebase, Wickes, ASDA, Sainsburys, Tesco and Morrisons have all stopped selling it!!! They tell me its because they are now 'green' retailers!?!? I think the earlier comment about bombs is more likely!!
I eventually found some 9.5% ammonia solution at Toolstation, they are a national company and it seems the only place that are going to keep selling it!!
