I did quartzscape in Anvil which is the darkest color made and we've done an acid bath and the calcium deposits are worse now than they were before. I'm guessing we need another acid bath and I think we are going to by the pHin and cancel our pool service because they clearly aren't getting the levels right. I'm going to head to the pool supply tomorrow and get the water tested and hopefully get this under control. I'm also going to reach out to my contractor for another acid bath. I love the color and maybe I won't obsess so much a year from now but with a 4 month old pool I really just wish it looked perfect!
