Write down what you added as well as what you measured.
Log backwashing and filter pressure weekly.

What is on the sheet

2 pages, in this order:

Page 1

Printed under the title: A daily and weekly water chemistry record for a swimming pool, so you can see a trend forming instead of reacting to a problem.

We record readings, we do not set targets. Target ranges depend on your pool's surface, sanitiser and local rules, and they are set by your test kit's instructions or your local authority — not by us. Record what you measure here and compare it against the guidance that applies to your pool.

Write-on lines: Pool · Volume · Sanitiser type · Surface / liner · Filter type · Season

Table, 20 rows: Date · Time · Free Cl · Total Cl · pH · Alk. · Cal. hard. · CYA · Temp · Chemicals added

Page 2

Weekly plant maintenance

Table, 14 rows: Date · Backwashed · Baskets emptied · Brushed / vacuumed · Filter pressure · Notes

Ruled lines: Notes and anything specific to yours

Questions

What should the readings be?

Target ranges depend on your sanitiser system, the pool surface and, for commercial or let pools, local rules. Your test kit instructions and your pool supplier are the right source — this sheet records what you measured, it does not set targets.

Why record filter pressure?

A rising pressure over time is the clearest sign the filter needs backwashing or cleaning, and it is only visible if you write it down.
