Rainy season in the Philippines and the rainwater is lowering our Poolwater ph to 6.8 from 7.5 so I had to add 1650 grams of soda ash.
If the rainwater stays t least for a while on top of the chlorinated water, an overflow drain tube could drain the excess rainwater.
So what floats on top? Does anyone has an answer to that?
I use granulated trichlor about 5 or more ppm.
