Pool Advisor version 2.5 was released this morning! In this release, you can now track the chemicals you are using and view them in a log. Previously you could enter the chemicals, but not have a history.
Coming up in the next release will be custom fields for Inventory and in the testing areas (Paid and Pro versions only).
Let me know if you have any other ideas for Pool Advisor!
