Hi.....I ahve been told by my local pool shop where I get my chemicals that Calcium is not needed in my pool even though it is extremely low. The pool is old and need to be resurfaced and there are patches where the marcite is going away.
They said since my surface is already damaged in areas that the Calcium is pointless now.
I would like to know your thoughts as I would think it would still help prevent much further damage over the next 5 years before I decide to do the pool.
Thanks!
