How Do I Raise Pool Hardness

[dpdeleon]

Hi,
I'm just learning what chemicals to use and the chemical balance of my pool. I've got a question about CH.
Using my taylor kit I am at 300 for CH. Should I just go to the pool store and purchase something to raise the CH or is there something else I can use?
Thanks,
denis

300 is fine for a gunnite pool, not sure what you are looking for? Do you have the PoolMath app?
