| FC | Goal: Not Setup | Add of% bleach. Jug size .
or add by weight or by volume of .
Note: Dichlor and trichlor add CYA and lower pH. Cal-hypo adds CH. |
| |
| pH | Goal: Not Setup | Given TA of and Borate of:
Add by weight or by volume of washing soda or soda ash
or add by weight or by volume of borax.
Add of muriatic acid
or add by weight or by volume of dry acid.
Note: pH calculations depend on TA and Borate. Results are approximate and can be off significantly for large pH changes. Changing your pH will also change your TA. |
| |
| TA | Goal: Not Setup | Add by weight or by volume of baking soda.
To lower TA you reduce pH to 7.0-7.2 with acid and then aerate to increase pH.
Note: Adding baking soda will also raise your pH. |
| |
| CH | Goal: Not Setup | Add by weight or by volume of calcium chloride
or add by weight or by volume of calcium chloride dihydrate.
To lower CH you replace of the water with new water, with CH of. |
| |
| CYA | Goal: Not Setup | Add by weight or by volume of stabilizer
or add of liquid stabilizer.
To lower CYA you replace of the water with new water.
Note: It can take solid stabilizer up to a week to dissolve. It will also lower your pH. |
| |
| Salt | | | Add of salt.
To lower Salt you replace of the water with new water. |
| Borate | | | Add by weight or by volume of
and of 31.45% muriatic acid to compensate for the pH increase.
To lower Borate you replace of the water with new water.
Note: The pH should be tested and adjusted as needed after increasing the borate level. |

Less than -0.6 is suggestive of problems for plaster, tile, stone, and pebble pools.
Greater than 0.6 is suggestive of problems for all pools. |
| Suggested FC Levels | SWG: Normal: to Shock: Mustard Algae Shock:
Suggested target FC levels based on the current CYA level for outdoor pools.
Note: Be careful if your CYA is really and truly zero! |
| Suggested Goal Levels | Use suggested goal levels from:
Primary source of chlorine: Pool surface:
Note: Suggested goals are simply a starting point. There are many situations that are not covered by these basic guidelines. |
