My pool is gunite--is that the same as plaster? The pool is an older one, I would say 15 plus years. We were told earlier in the season by my ex-pool guy that we needed new gunite at about $6000 --cant afford that at this time so we are making do with what we have. There is some pitting-nothing bad that I can tell though. What is wierd though is that if I check with strips it shows my hardness at 400, but with the drop kit the water does not even turn red.
Just re-tested my hardness with drops(added cal-hypo last night) and the water turned a very light shade of pink. After 40 drops of titrant the water turned a very light turquoise blue. So now maybe I have some hardness? When I add the 5 drops it sinks to the bottom and I have to stir to mix--is this ok?
Thanks
Karen
