How to Choose the Right Pool Chemicals for Your Setup

How to Choose the Right Pool Chemicals for Your Setup
Introduction

The selection of pool chemicals requires more than basic chlorine purchase. Each swimming pool presents its own characteristics such as dimensions and surface type and usage habits and water origin. To achieve safe water conditions you need to find an optimal mix of sanitizers and balancers with supplements.

Deep Blue manufactures a complete selection of professional-grade pool chemicals including chlorine and bromine and environmentally-friendly oxygen-based alternatives. We offer easy-to-use dosing tools together with helpful guides and expert support to help you find the appropriate mix for your pool requirements.

Step 1: Know Your Pool Type and Size

Above-ground vs. in-ground: Smaller pools require less product but often need more frequent attention
Surface material: Vinyl, fibreglass, and concrete react differently to certain chemicals
Volume: Accurate pool size in litres is crucial for correct dosing — use our free pool volume calculator

Step 2: Choose Your Sanitiser

Chlorine

The most common and cost-effective option. Ideal for most setups.

Chlorine Tablets: Slow-dissolving, easy maintenance
Chlorine Granules: Fast-dissolving, great for quick top-ups

Bromine

Best for spas and warm-water pools. Less irritating and longer-lasting in high heat.

Oxygen-Based (Non-Chlorine)

Suitable for individuals who have chlorine sensitivities or those who want to adopt eco-friendly solutions. It performs best in smaller pool setups or as an addition to UV/ozone system applications.

Step 3: Test Your Water Regularly

Deep Blue’s digital testers and test strips provide you with the necessary information to assess:

pH (7.2–7.6)
Total Alkalinity (80–120 ppm)
Calcium Hardness (200–400 ppm)
Cyanuric Acid (30–50 ppm if using stabilised chlorine)

Step 4: Select Balancers and Supplements

pH Adjusters

Use pH Plus or pH Minus to keep water balanced. The improper balance of pH levels causes harm to equipment while simultaneously lowering sanitizer effectiveness.

Alkalinity Plus

Stabilises pH and prevents sharp swings.

Calcium Hardness Increaser

Soft water areas require this solution to prevent corrosion especially when pools have concrete or plaster construction.

Algaecides

Preventative care that keeps your pool clear in hot weather or high-use periods.

Step 5: Consider Specialised Products

Non-Chlorine Shock: Regularly oxidise contaminants
Winterisers: Prepare for pool closure
Clarifiers: Help clear up cloudy water fast
