# Lab water test

A lab water test is a full water analysis from a pool store or a service company.

A lab test checks more than a home kit. It can include metals, [phosphates](https://marinapool.multisites.ai/glossary/phosphates), [dissolved solids](https://marinapool.multisites.ai/glossary/total-dissolved-solids), and [cyanuric acid](https://marinapool.multisites.ai/glossary/cyanuric-acid). It helps when the water is cloudy, stained, or green and home tests do not explain why.

Bring a fresh sample from elbow depth, away from the skimmer and returns. Use a clean bottle and test it within an hour or two. Ask for printed results, then adjust one thing at a time. Do this at least at the start and end of swim season.
