Poolmaster Replacement Indicator Solutions #1–#5 for Spa or Pool Water Testing – Neutral, Small

Effortless water testing for pools and spas

Poolmaster Replacement Indicator Solutions #1–#5 provide a practical, easy way to observe how your pool or spa water chemistry shifts over time. Designed to pair with select Poolmaster test kits, these neutral solutions help you track five essential factors that influence water balance and equipment performance, making routine maintenance simpler and more predictable.

What you test and how it helps

Consistent testing supports clear water, comfortable swimming experiences, and dependable equipment operation. The five factors measured are:

• Chlorine
• Bromine
• pH
• Acid demand
• Total alkalinity

By observing color changes in your test kit, you can gauge when readings swing away from your target range and plan mindful adjustments rather than guesswork. Use these indicators as a helpful cue to schedule balancing steps during regular maintenance or before hosting guests.

What’s included and important notes

The kit includes 1 oz. solutions of #1, #2, and #3, and 1/2 oz. solutions of #4 and #5. Important notes to keep in mind:

• Phenol Red is intended for use with 2- or 3-Way test kits only—not with 5-Way kits.
• Solution #1 is sealed to comply with transportation regulations; the remaining solutions do not require sealed caps.

How to use with your testing kit

Prepare your testing process according to your kit’s instructions, then add the corresponding indicator solutions to observe color shifts. Compare the colors to your kit’s reference chart to determine whether adjustments are needed and to guide routine maintenance steps.
