Pool chemical orders are tracked on this page. Do not post costs here as they may be considered proprietary to the supplier (not public).

Key:

  • The Order column contains the total number of units ordered for the entire season. If subsequent orders or made (beyond the pre-season order), this should be noted in the notes, below.
  • The Inventory column contains the total number of units on-hand at the end of the season.
  • The Usage column contains the number of units used during the season (prior inventory plus the order minus usage).

A "unit" refers to the package quantity (i.e. 50 lb, 1 gal, etc.).

Notes

Pre 2021

Chemical orders were not well tracked. Early season discounts not fully utilized due to repeat orders (sometimes up to 5 orders in a season, also resulting in added delivery charges).

2021

The chemical order was based upon 2016 through 2019 averages. The end result was a planned excess of some chlorine and acid. No additional orders for chlorine and acid were made, so the pre-season discounts were fully utilized.

However, excess purchase of sodium bicarbonate was necessary to keep the pool alkalinity in range (compared to data from 2016-2019). The amount of stabilizer in the pool was also regularly low.

2022

For 2022, there is no need to purchase calcium chloride.

Chemical orders for 2022 are under pending review in early spring (2022).
