Using 20 mule borax and baking soda

You cant be serious. Go back and read some posts on what to do first, and wait for some one to reply.

The first thing to do is this:

But there's a catch--you have to have a good test kit, and use it regularly.

While it's not out of the question that you might need to use that much borax to raise your ph - I had to use 2 1/2 boxes of borax to raise my ph from 6.9 ppm to about 7.4 ppm for a 14,000 gallon pool - it's never a good idea to add a lot of chemicals without having a better idea on what your chemical levels are. The dipstrips aren't accurate enough for this.

I sprinkle powders and pour liquids into the pool where the water re-enters back into my pool.

pcasey -- Before any of us are really going to be able to help. we need current water testing results taken with a drops based kit. Then, we can help you go from there.

As far as how to add borax and baking soda, you can do as b2001 suggested above and add them to the water at the pool return or you can slowly pour them into the skimmer while the pump is running. That is what I do with my pool. Post back with current numbers and somebody here will try and advise you.

One other thing, in a pool your size, the volume is more like 12,500 to 13,000 gallons instead of 15,000.
