Buying Guide

Key purchase considerations for outdoor fountain water treatment:

  • Scale and mineral buildup: Choose products that specifically target lime and calcium deposits to protect pumps and surfaces, especially in hard water zones.
  • Algae control: If algae is a frequent issue, prioritize algaecides or multi-action formulas that prevent growth and clarify water without harming wildlife.
  • Maintenance level: Some treatments require regular dosing, while others offer multi-action blends designed to reduce maintenance time.
  • Compatibility: Verify that the product is safe for the materials used in your fountain (stone, metal, glass, plastic) and for animals near the water.
  • Odor and clarity: Enzyme-based clarifiers can improve odor and visual clarity by breaking down organic waste without harsh chemicals.
  • Application method: Consider whether a product is easy to apply directly to water, or requires pre-dissolving or specific dosing routines.
  • Environmental impact: Opt for products with low VOCs and formulations that are safe for birds and pets when used as directed.
  • Climate considerations: In warmer, sun-soaked climates, algae and bacterial growth can spike; select preventive treatments suitable for year-round use.

Overview of selection scenarios:

  • Clear water with minimal maintenance: Pick a multi-action treatment that combines clarifying agents with scale prevention, such as PREVENT or a comprehensive clarifier.
  • Frequent scale buildup: Use a dedicated scale remover or scale-prevention formula to reduce mineral deposits over time.
  • Algae challenges: Prioritize an algaecide or enzyme-based clarifier designed to prevent and reduce algae growth while keeping the water safe for birds and pets.
  • New fountain installation: Start with a clarifier to establish clear water quickly, then transition to preventive maintenance to sustain clarity.
