Even close to the tub, there's still a big bucket of very acidic water to hold at torso height to then distribute around the tub. One slip, and it's acid all over the torso. That's just my personal fear. Also, when stirring the solution to dissolve, there's an acid splash risk. Surely this represents way more risk than necessary, when the tub's naturally gonna agitate the acid granules into solution pretty good (especially with a much bigger body of water)? Makes sense, but surely with the (relative to a pool) the heat and agitation of a hottub with blowers on, surely they should dissolve pretty quickly? I guess my question for you (where user adds dry acid to the tub undissolved) is twofold: - Is the risk: (a) damage to hottub components or, (b) damage to bather due to a pocket of highly acidic water and - If the risk is to the bather, then assuming bather & chemical balancer is the same person: Which is the greater risk/ register of likelihoods? Sorry for asking more questions, I am just trying to understand better.... Am I the only person paranoid about this issue 😅 ... I just hate having to regularly deal with a 5 litre bucket of extremely acidic solution. The weather where I am is regularly rainy, I have decking one side (which can get slippery as a result); steps; and on the other side loads of slick muddy grass (for half the year).

Hi Waterbear, first off, Merry Christmas! I've been a long time lurker on these forums and you (and a couple of others) have saved my bacon time after time with the knowledge you share. My question is about adding dry acid (as pH-) into my hottub. I really don't like pre-dissolving in a bucket, as my ground can be super slippery (plus stairs down to tub etc) and it worries me that I'll spill the highly acidic solution on myself/the dog/plants! SO I really would prefer to dose directly into the tub, but I've always been dissuaded from doing so by reading bottles, reading forums & listening to hottub store advisors. From your quote above I understand that in a hotub it is probably OKAY to add the dry acid directly into the tub (due to the inherently good circulation). Using this method, would you advise dosing the dry acid around the perimeter presumably, and how long would you leave the blowers on to help it dissipate before testing/using and would you test from the centre of the footwell for instance for certainty of dissipation, or shouldn't it matter? Thanks so much and apologies for bringing this old thread back from the 2012 dead!
