I was wondering if anyone knew the lower limit of acid concentration you can get away with to make ap... The forum I think says 30 percent but has anyone tried it with lower concentrations and got it to work?

You certainly don't need 30%, nearly any concentration will work although you may have to use more in order to have enough ions to catalyse the reaction.
Most people use around 30% HCl as this is the concentration is commonly comes in.

I always use 10% HCL in my dreams works fine
(And i don't use more)

I have been making my AP using 20% muriatic acid. Im not sure but I think muriatiac acid is just another name for HCl or are they different?

What about Citric Acid? there seems to be very little information on the use of this supermarket acid. SWIM tried making ap with citric acid (150ml 6% HP + 50mls pure acetone) there was a tiny bit of heat produced but no cystals the next morning (or afternoon, 20hours after first mixing) so SWIM then aded some (ALOT) more citric acid crystals untill they had trouble dissolving and is awaiting further results

I just posted my results on the use of citric acid and acetic acid in AP production in The AP beginners Guide. Basically it does not work. (Only inorganic acids do). Has anyone tried NaHSO4, commonly sold as dry acid for pools. It hydrolyses quite nicely for other uses and is alot stronger than acetic or citric acid.
