Welcome to our forum.
What is your method of testing?
With TA at 150 why even worry about it? It's an acceptable range IMO..
The next best thing would be to use 20 Mule Team Borax since that will raise the pH without increasing carbonates so raises the TA by half as much as pH Up. However, if you use that a lot, then you may add too many borates -- up to 50 ppm cumulative is OK.[\quote]QuoteAs for pH Up, that is sodium carbonate and is identical to Arm & Hammer Super Washing Soda (careful: NOT the laundry detergent) which you can obviously get for a lower price at grocery stores and is used to raise the pH though also increases the TA as well. Alkalinity Up is sodium bicarbonate (aka sodium hydrogen carbonate) and is identical to Arm & Hammer Baking Soda and is used to raise the TA (it can also raise the pH if it is low, but is not as efficient in doing so). If you want to raise the pH with half the rise in TA, you can use 20 Mule Team Borax.[\quote]QuoteBorax raises the PH without affecting the alkalinity.No it's not soda ash but it's close chemically to it. There is a website for pools that have people using bleach for chlorine, borax for PH up and baking soda for pool store alkalinity increaser ... baking soda[\quote]
