Is this Normal ? New Hydrazzo pool finish - blotching

[Redeye1976]

Hi All , pool is 4 months old and has Hydrazzo finish and notice it’s blotchy in many areas in terms of color and some spots are discolored and rough / is this normal ? Pool builder is claiming water chemistry and it’s a weekly thing to keep PH down and have had issues with calcium flaking , especially when pool temp hits 94 degrees . I want to know if PH is valid for calcium issues but the surface being blotchy is that water chemistry of how it was applied ??

Water chemistry has nothing to do with mottling.

What do you mean by "calcium issues".

pH does not but CSI of which pH is a component does.

Calcium Saturation Index (CSI)

How is CSI calculated? Very simple – use our PoolMath tool. To ensure long plaster life and save money, click here to learn more.

Being Blamed for Plaster Discolorations? Don't Get Hoodwinked

Some newly plastered pools (including quartz and pebble finishes) may develop either color fading, white soft spotting (also incorrectly called "spot etching" by some plasterers), white streaking (in colored plaster), calcium nodules, gray mottling discoloration (of white plaster), spalling...
