I just filled my pool, with pretty much all rainy water. my CH is 50. Should I really aim to raise this level ? I am not even sure I can find the right chem for that where I live. And if so, what's the minimum CH level I should bring the water to ?

You want a plaster pool to have CH of 250-300ppm. If you can get calcium hypochlorite then you can use that to raise your FC.
I found this thread on alternatives to pool store calcium increaser by doing a google search at the bottom of this page. If this thread doesn't help you may try searching for another.


We use calcium chloride when we bring a pool down a little too far :oops: Easy and relatively inexpensive.
