Acid container was damaged and had been taped over. I also bought some from the store too and it works better than using dry acid. I still wear protective gear such as a 3M vapor mask, saftly glasses and chemical gloves to be on the safe side. I found a spout for it and pour samll amounts in front of the jets while the pump is on so it circulates and just dosen't fall to the bottom as it weights more than water does. I am not going to mess with handling it twice because I am diluting it as I add to the pool water anyway. I do move it around so not to pour to much in one spot either and again I do have a protective gear on. I learned it is suppose to take 25.6 oz of 31.45% acid to lower TA 10 ppm in a 10,000 gal pool. This container is 128 oz so that means 1 gal has the potential to lower your TA 50 ppm. I can't say I am getting those exact results, but it did lower my PH from 8+ to 7.4. Of course you have to watch letting ph get to low before areating to increase PH and then you can contine to lower the TA by using more acid. I feel like Dr Frankinstien! One thing I recently learned is number 1 priority is making sure you have enough FC chorine in your water first because it oxidizes and if it doesn fully accomplish that. it does not convert the chlorine chemical into HCI a form of acid that reduces PH/TA, then move onto PH/TA testing etc.update: I read somewhere Acid Magic strength is 31.45% my experience is it is not correct. There is no % amount stated on the container I look at mine because you can't even zoom in on the label here. After I test my ph with Taylor regents and then reference their guide for 31.45% muratic acid, it tells me how much to add to reach the desired PH level. It takes me twice the amount of Acid Magic, so it's not only less fumes and doesn't burn, it is weaker too, I'm guessing 28 - 15% area so you will use more but it works better IMO than dry acid which is expensive too. I won't use the regular harsh acid which is more dangerous to handle. I did find the Acid Magic will ruin an mental like a razor or skew driver you might use to get the seal off with. I didn't even touch the liquid just the seal so it is quite corrosive.
