I recently got Ph plus but the amount that is has for pool care is very small 1/3 of a cup for 1,000 gallons of water. So how much do I want to raise my 2 gallons of water for my tie dyeing? Or how much soda ash do I use? Thanks
If the fine print on the label says that it is sodium carbonate, then you can use the exact same amount as you would normally use of soda ash. For tie-dyeing I use one cup of soda ash per gallon (250 ml per 4 liters), but half that will usually work fine.
Rarely, stores will sell sodium BIcarbonate instead of sodium carbonate as pH Up. You don't want sodium bicarbonate (unless you're steam-setting afterwards).
