Operating and maintaining an aerobic system requires you as the homeowner to add chlorine to your septic system. If you choose to use liquid chlorine, you can dilute it without rendering it ineffective.

Recipe For Diluting Bleach

Diluting your bleach is not required, but if you’d like to save a few extra dollars we recommend diluting concentrated liquid bleach with 2 parts water and 1 part bleach.

Note that I said concentrated bleach. If the bleach you purchase is labeled “regular strength” instead of “concentrated,” you should not dilute it.

Warning: Do Not Use Pool Chlorine

Do not use pool chlorine tablets or liquid in your aerobic system — it’s ineffective at treating wastewater, and over time can build up enough nitrogen chloride to cause an explosion.
