Wow, that sounds pricy for startup!! It sounds like you know the routine- keep the PH down with muriatic acid and brush 2 to 3 times daily. Clean the filter every 3 or 4 days to keep the plaster dust cleared. Check the PH every day because new plaster will tend to drive it up and you'll probably need to add acid almost daily for a while. Run the pump on high speed 24/ 7 for the first 2 weeks. Don't run your cleaner the first 2 weeks, it can damage the plaster.

My PB told us to keep the pump on high during brushing, but the chop on the surface made it hard to see what I was doing and I missed some spots. I suggest cutting the pump while you brush the sides, then push the dust towards the drain. When you get within a few feet of the drain turn the pump on and push the dust into the drain until it's gone. That's what I did the 2nd week and it was a lot easier to see what I was brushing. The dust will be back a few hours later, that's why you have to do it a few times a day :-)

Its exposed aggregate....I'm actually not seeing that much plaster dust at all after 24 hours. Brushed 3 times today....and on the last time, there was hardly any at all. The sequestering agent they suggested is suppose to bind the dust as well though according to the distributor of the Stonescape material. Water is clear down to the bottom of the pool... In fact, I can see all the plaster imperfections.... ;)

Yeah, there's not as much dust with pebble finishes. Stick with the brushing though, if you only brush sporadically you can still get a haze develop from the creme. The first few days are the most important.
