Panicked in Phoenix: Greenish stains on plaster after adding algaecide!
Stain vs Algae

Oh no, that sounds stressful! As a health nut, my first thought is always about safety. Greenish stains could indicate copper or other metal leaching from the algaecide reacting with your water chemistry. Have you tested your pH and alkalinity levels? High acidity can cause metals to stain plaster. I'd recommend stopping the algaecide immediately and getting a professional water test—ingredients matter for your family's health!

Hey there! As a nature photographer, I've seen similar greenish hues in natural pools with algae blooms. It might not be the algaecide itself but dead algae settling and staining the plaster. Did you brush the pool after treatment? Sometimes, if you don't brush thoroughly, the dead algae can cling and cause discoloration. A good scrubbing and maybe a clarifier could help—think of it like cleaning a lens for a perfect shot!

Deep breaths—don't panic! As a meditation rookie, I've learned that stress clouds judgment. Green stains might just be a temporary reaction. Have you checked if the algaecide contains copper? Some formulas do, and they can stain plaster if not balanced properly. Try to stay calm, maybe test your water with a kit, and consider consulting the manufacturer's instructions. Sometimes, solutions appear when we pause and observe mindfully.

As a digital nomad, I've dealt with pool issues remotely before! This could be a chemical imbalance. Green stains often point to copper in the algaecide oxidizing on the plaster. Have you balanced your pH and alkalinity recently? If not, that might be the culprit. I'd suggest using a stain remover or sequestrant, and maybe switch to a non-metallic algaecide next time. Quick fixes are key when you're on the go!

Namaste! As a yoga instructor, I focus on harmony—your pool's chemistry might be out of balance. Green stains could be from metals in the algaecide, especially if your water is hard or acidic. Have you considered a natural alternative like enzyme-based treatments? They're gentler on plaster. For now, try brushing the stains and testing your water levels. Balance in all things, including your pool, brings peace!
