RedCourt Posted March 15, 2013 Report Share Posted March 15, 2013 My new tub is a reconditioned Caldera Geneva w/ new pump and heater. Electrician connected it today and my plan had been to do Nitro's decontamination and follow that with his outlined Dichlor water maintenance method. The guy I bought it from (former sales rep for two different spa companies) lost it when I mentioned planning to use Muriatic Acid. (It sounds like a better choice than sulphuric to me) According to him that's a HUGE no-no in an acrylic spa... I tend to think I would have run across more discussion about that here if it was really such a huge thing. Is there an entirely different water chemistry protocol for acrylic above ground spas? Or is he just used to touting the company line and selling branded products? (That's my guess) Quote Link to comment Share on other sites More sharing options...
Dr. Spa Posted March 16, 2013 Report Share Posted March 16, 2013 What is your intended purpose for using muriatic acid? Quote Link to comment Share on other sites More sharing options...
RedCourt Posted March 16, 2013 Author Report Share Posted March 16, 2013 I would be using it to lower the pH when necessary per Nitro's water maintaince guidelines. Quote Link to comment Share on other sites More sharing options...
waterbear Posted March 17, 2013 Report Share Posted March 17, 2013 only problem is that because of the small water volume is it very easy to overdose and difficult to measure since you would only be needing teaspoons of the stuff. Dry acid (sodium bisulfite) is a better choice since it is easier to handle and measure. Other than that there is no reason why you cannot use muriatic acid.

RedCourt Posted March 18, 2013 Author Report Share Posted March 18, 2013 Thanks waterbear! I decided on muriatic acid because I didn't want to increases the sulfate level unnecessarily. I'm used to dealing with micro qty's in other areas of alchemy so I think I'll be ok. Glad to know that the guy I bought it from wasn't all that well informed. Neither was the guy at the Pool store when I was looking for boric acid, blank stare then tried to sell me their branded system. LOL Quote Link to comment Share on other sites More sharing options...
