Monitor

From first principles, it’s clear that continuous electronic monitoring of water quality is a huge step up from periodic manual checks. Traditional “test strips”—where you dip the strip and squint at the color—leave a lot to subjective interpretation and gaps in data.

Instead, look for a product that:

• Supports open wireless protocols for easy data access,
• Floats in the water for hands-off operation,
• Is solar powered for sustainable, low-maintenance use.

If you find a good product, get a backup. The “power of two” rule applies: always have a spare. Cayman sun is punishing on everything—especially electronics—and the harsh environment will eventually destroy even the best equipment. Plan for your device to fail not if, but when.

Having two devices also lets you cross-check readings and spot faults quickly, ensuring your monitoring system stays reliable.
