Hello Folks
We have just built a pool and put water in it at the end of August. It is a shotcrete pool with Hydrazzo French Riviera. About a month later we saw streaking on the sides. We contacted the Builder and he immediately said that it is because the pool water chemicals were not correct. He brought over a representative from Hydrazzo who said that pool PH was more than 8 and that has left a calcium streaking. He recommended using Jack's Magic stain solution #2 treatment. The Builder has done that but it appears that the Calcium streaking has gotten worse. Attached are some pictures
Has anyone experienced this? Any suggestions?
TIA
