  • Baking soda versus borax - Trouble Free Pool
    Washing Soda = big pH change, big TA change Probably more TA change than you want Depending on our conditions, it is best to get your TA to 50+, then use aeration to raise the pH Chemically raising pH is rarely necessary
  • Pool Math
    If the depth varies, use the average depth of the pool A good approximation is the shallow end depth plus the deep end depth divided by two Irregularly shaped pools can be approximated by estimating the average length and width and using rectangular
  • soda ash - Trouble Free Pool
    Washing Soda is still significantly less expensive unless you buy soda ash in very large quantities
  • increasing pH and TA - Trouble Free Pool
    My pool math app suggests I add 8 oz soda ash or washing soda to increase my pH (Taylor test kit tested @ 7 0) and 3 # baking soda to increase my TA (tested @ 30) Should I add both together or start with the baking soda and see how it goes? Can I use regular Arm and Hammer Baking Soda? Thank you
  • Arm and Hammer Super Washing Soda vs. Soda Ash
    The type of sodium carbonate used in washing soda is a decahydrate, so you need to use a lot more washing soda than you would anhydrous soda ash One should use 2 7 times as much washing soda as a substitute for soda ash, if measuring by weight, or 4 6 times as much if measuring by volume
  • HELP!! Used Washing soda as directed, now I can do my laundry!!!
    I was trying to raise my PH, and normally use regular baking soda but noticed the app suggested super washing soda Now the water is slightly green and basically overflowing with suds What the heck? I guess drain and refill is the only thing I can do at this point? View attachment 632957 View attachment 632958 View attachment 632959 Click to
  • Arm Hammer Washing Soda? - Trouble Free Pool
    I've seen this product as well, but it was sold in the laundry detergent section and didn't say Arm Hammer Super Washing Soda that is used as a laundry booster and is pure sodium carbonate
  • PH or Borax - Trouble Free Pool
    pH-UP is basically a more expensive version of washing soda, aka, sodium carbonate It raises both pH and TA very strongly Borax is sodium tetraborate decahydrate It raises pH strongly but only adds a negligible amount to TA Even if one borates their pool to the recommended level of 50ppm, the additional TA increase is minor (about 5ppm or so)
  • Managing pH and Total Alkalinity - Further Reading - Trouble Free Pool
    Baking soda has a small impact on pH and is the preferred method for increasing TA If you need to raise your TA and decide to use Washing Soda or Borax, understand that it will raise your pH somewhat significantly
  • baking soda vs washing soda - Trouble Free Pool
    The Pool Calculator recommends a value to add to raise PH using washing soda (sodium carbonate) I have a very large bag of sodium bicorbonate (baking soda) left over from the previous owner and am wondering about using that It's my understanding that sodium carbonate is more caustic than
